May the uninitiated and the partially initiated receive inspiration, and may the disciple receive knowledge. Shiva resides in sahasrara. Shakti lies dormant in the triangular yoni which the shastras also call "kula-kun-dala" or "matri-yoni". "Kula" means ''shakti" or "power" and "kunda" indicates "yoni". Kundalini, which is more minute that an atom is coiled three and a half times, and lies dormant within man's body.
Sahasrara is the abode of Shiva, where Shiva and Shakti live in full harmony. Here we find the ocean of nectar flowing, and just below this is the bindu visarga. It is at this point that the human being becomes an achiever, a partial achiever, and finally a non-achiever. At this very place the great Shiva resides in the form of light, and when the cover of ignorance is removed, all the three worlds awake. This is the place where all the desires arising from the collected karmas, life after life are deposited. This is the place where the much-coveted "kalpataru" (the imaginary tree which fulfils one's desires) is to be found. This is the altar where Shiva and Shakti unite.
The power of kula-kundalini lies in mooladhara in the form of body consciousness, in swadhisthana in the gross form, in manipura as the gross form which tells us about the sense of smell, in anahata in the gross form which tells us about the sense of touch, in vishuddhi in gross sound, in ajna transgressing the thought waves of the soul, and finally submerges in sahasrara.
When kula-kundalini awakens like an angry hissing serpent, body consciousness, inner consciousness and ego all disappear. Then yogic powers start running behind the yoga aspirant like an old man being chased by girls wearing no clothes. Now the Guru alerts his disciple because the achievement thus gained can be lowly temptation. This is called "Tripura Sundari" because it covers the gross, subtle and causal body. A person who knows the truth behind this transcends all the three worlds. The moment kundalini touches anahata chakra, the lotus heart blooms.
If, under the guidance of your Guru you learn to meditate with the mantras "Ka" "Aee" "Ee", "La", "Hrim", then you can master the all-pervading and protective powers of Kameshwari, Modini Vimla, Aruna, Jayeeni, Sarveshi and Kaalini, as described in the "Ashtachara".
Kula-kundalini is the power of Shiva which destroys the lust for life. The psychic emotions of a yogi are obliterated by this Three bindus, three triangles, three parallel lines, a. mantra with three alphabets, three manifestations, three yonis, three specific powers, such is Tripura Sundari.
These three bindus: red, white and colourless, signify self-control, the sense of being and the sense of existence. The first bindu (red in colour) signifies ego-consciousness, the second bindu, (white in colour), signifies manomaya consciousness, and the third bindu signifies the formless consciousness (hence it has no colour).
Meditate on the kula-kundalini in mooladhara as though the three bindus were a smiling faces and two breasts, and the "Ha" form resembles the lower parts of the body. Now meditate on the "Manamath Kala". By this you will achieve Shiva consciousness. Now the Guru warns the disciple that all this is ephemeral and the benevolence of Tripura Sundari alone is eternal.
Meditate on the kula-kundalini in the anahata chakra because there the nectar is flowing. By doing this all the elements of sin are eliminated. Go along with your Guru, transgressing earth, water, fire, air and ether elements, remain in pure consciousness.
By the help of "Hatha" mantra and emotions the intensity of human feelings is extinguished.
If you are beside your Guru you will give up the three spheres, the seven realms and the fourteen "bhavanas". On the way you will encounter Brahma (the Creator), Indra (the god of rain), Yama (the god of death) and Kuber (the god of wealth) whom you have to destroy, and you have to go past their realms.
First you have to pacify the kula-kundalini whose origin is in the yoni, and whose path is along the sushumna and which unites with Shiva at "brahmarandra". Now, with the help of unbroken day and night japa, with steady dhyana, non-dual feeling for your ishta, blessings, living on fruits, total subjugation, wooden silence and strict celibacy, you can elevate the kula-kundalini. For elevating the kula-kundalini chant the "Durga Saptashati" or "Ananda Lahari".
To help the kula-kundalini rise upwards unobstructed, practice asana, pranayama, mudra and bandha so that the "brahma granthi", "vishnu granthi" and "rudra granthi" can be overpowered, and all three gunas can be subjugated, because she stands on the corpses in the forms of Mahashakti, Mahakrodha and Avadhoot. In such a condition, only a real Guru can give support to his disciple. A Guru who has no experience of Vamakeswar Gyanaargava or the Tantras should not take the risk of guiding an aspirant.
First and foremost, after preparing a sacrificial pit, "havan kund" the Guru should make offerings to the fire with scented ghee a hundred times, or the disciple should make offerings a hundred times to the luminous "swayambhu linga" situated in the kula-kundalini.
The Guru should make a sacrificial fire in the north and another opposite it, and with the help of his disciple he should kindle a fire by attribution called "swayambhu agni".
When the sacrificial fire is lit, more firewood should be added to it, and while meditating upon Manmatha Kala and Vashini Kala every day, offerings to the fire should be made a hundred times.
When these offerings to the fire are being made, the three bija mantras of "Ka", "Aee" and "EE" should be joined to the "panchakshari" (five worlds for chanting mantras) and the disciple should be made to chant these mantras. The offerings to the fire should be made with full alertness.
The Guru makes offerings to the fire. Once again the disciple kindles the fire by attribution. Now the disciple while manifesting Manmatha Kala in the kindled kund (where the fire is ignited) and concentrating steadily on the ishta devata, (ishta devata is like a god who is your personal god, like a patron saint), should chant ''Om, Ka, A, Ee, La, Hrim, Ha, Sa, Ka, Ha, La, Hrim, Sa, Kam, La, Hrim".
There is one thing that I will point out. This mantra should be chanted one thousand times. The Guru and disciple perform a powerful "poornahuti" (the last offering to the fire at the end of the havan) because what happens is that the container in which the scented ghee for the offering is kept cannot be kept steady throughout the repeated chanting of the mantras a thousand times. If either of the two (Guru or disciple) loose their concentration the sacrificial offering becomes prematurely broken.
As long as the fire keeps burning, and both are ready for the sacrificial offering, they should both remain in "kumbhaka" and with great perseverance they should plant their prana in the container where the havan articles are kept, and in the flames of the sacrificial fire, and then awaken their prana with great perseverance. Till the time when the Guru performs the "poornahuti" the disciple goes on performing the last ritual with great devotion and sincerity.
After that, both the Guru and the disciple should meditate in swadhisthana, on the ishta devata, and become calm.
If you are an able, experienced, powerful and restrained disciple you can perform this "yagya" on your own. This practice of Tantra cannot be performed by the Guru alone. This secret practice of Tantra should be done only by a powerful and restrained Guru and disciple otherwise every time the sacrificial offerings will go in vain.
Only yogis can perform these rituals from Tantra or else the fear of revocation is inevitable. Hence you should make your soul free from sin, fearless and pure. An aspirant who is not a brahmachari can never be successful in this ritual.
The awakening of Shakti, awakening of the chakras and the union of Shiva and Shakti can only be achieved by perseverance, mantra and meditation.
Guru and disciple should have perfect practice of "shambhavi mudra", "agochari mudra" and ''bhoochari mudra", or else they should resort to drugs.
Kundalini is indestructible. In all the six chakras their grandeur assumes the form of "rakini", "lakini", ukakini", "shakini" and "hakini", and control these chakras. They are the Shaktis or the presiding deities.
You should pray to Savitri and Brahma who reside in the triangular yoni in mooladhara, which in the kundalini has an "aakar" form. This is the "kaula" (family) tradition. Including swadhisthana this is also called the "tamas chakra". Hence do not be satisfied by achieving. Restrain, and make sacrificial offerings till the power (situated in mooladhara) leaves its place and rises higher.
In swadhisthana, pray to Rudra and Rudrani. Also meditate on your ishta devata till your ishta reaches the realm of Varuna.
Now, in the realm of Varuna and manipura chakra symbolised by a lotus situated in the navel region, pray to Vishnu and Narayan. Be very careful now because here primordial longings awaken with the help of passion. May Guru protect you.
Now, with the help of mantra, perseverance and meditation, awaken your ishta and place him in the realm of Vayu.
Anahata is the realm of Vayu. There the heart is symbolised from which the sounds of ''Ham" and "Sah" constantly emanate. Anahata is known as "poornagiri peeth". God and Shakti are the presiding deities of this chakra. Although the nada originates from the yoni chakra, here it becomes "para nada". If you hear the sound of "Ham"and ''Sah" in the chakra you should consider yourself fortunate. The form of manipura nada is "pashyanti".
Now in vishuddhi chakra pray to the "ardha narishwar" (half woman, half man) form of Shiva and Shakti. This is "akash". This is also called the seat of jalandhar. With the practice of shambhavi mudra in this region only, do japa in the "vaikhari" form of "Ham" and "Sah".
Now, Oh Yogi! pray to agya chakra. Herein is the "itaraarvyaling"! Agya chakra is the region which controls prana and the mind. Behind this word, the feeling of touch, form, the sense of smell and dreams in the form of six circles, lie dormant in the manas chakra.
Beyond this is the realm of the sublime jyoti and Shiva. You will reach this place after agya chakra.
