Yoga is a perfect practical system of self-culture. Yoga is an exact science. It aims at the harmonious development of the body, the mind and the soul. Yoga is the turning away of the senses from the objective universe and the concentration of the mind within. Yoga is eternal life in the soul or spirit. Yoga aims at controlling the mind and its modifications. The path of yoga is an inner path whose gateway is your heart.
Yoga is the discipline of the mind, senses and physical body. Yoga helps in the coordination and control of the subtle forces within the body. Yoga brings in perfection, peace and everlasting happiness. Yoga can help you in your business and in your daily life. You can have calmness of mind at all times by the practice of yoga. You can have restful sleep. You can have increased energy, vigour, vitality, longevity and a high standard of health. Yoga transmutes animal nature into divine nature and raises you to the pinnacle of divine glory and splendour.
The practice of yoga will help you to control the emotions and passions and will give you power to resist temptations and to remove the disturbing elements form the mind. It will enable you to keep a balanced mind always and remove fatigue. It will confer on you serenity, calmness and wonderful concentration. It will enable you to hold communion with the Lord and thus attain the summum bonum of existence.
If you want to attain success in yoga, you will have to abandon all worldly enjoyments and practise tapas and Brahmacharya. You will have to control the mind skillfully and tactfully. You will have to use judicious and intelligent methods to curb it. If you use force, it will become more turbulent and mischievous. It cannot be controlled by force. It will jump and drift away more and more. Those who attempt to control the mind by force are like those who endeavour to bind a furious elephant with a thin silken thread.
A guru or preceptor is indispensable for the practice of yoga. The aspirant on the path of yoga should be humble, simple, gentle, refined, tolerant, merciful and kind. If you want to get psychic powers, you cannot have success in yoga. Yoga does not consist in sitting cross-legged for six hours or stopping the pulse or beatings of the heart or getting oneself buried underneath the ground for a week or a month.
Self-sufficiency, impertinence, pride, luxury, name, fame, self-assertive nature, obstinacy, idea of superiority, sensual desires, bad company, laziness, overeating, overwork, too much mixing and too much talking are some of the obstacles on the path of yoga. Admit your faults freely. When you are free from all these negative traits, samadhi or union will come by itself.
Practise yama and niyama. Sit comfortably in padmasana or siddhasana. Restrain the breath. Withdraw the senses. Control the thoughts. Concentrate. Meditate and attain asamprajnata or nirvikalpa samadhi, union with the Supreme Self.
