Bread, butter, jam and nice biscuits cannot give you everlasting peace. Comforts are enemies of spiritual life and peace. They pull a man down. After all, man wants very little on this earth. You will think of God only when you are in adversities. What is wanted is spiritual wealth which is inexhaustible. Happiness does not come from wealth. Spiritual life alone can give real, everlasting peace and happiness.
The mind is the substratum behind pleasure or pain, happiness or misery, success or defeat. Rise above the pairs of opposites by resorting to a guru and his instructions. Study the lives of saints who underwent various trials and read the books by realized souls. Develop the spirit of true surrender wherein you have no thought of body or bodily needs or self-protection even in the slightest degree and wherein you forget the idea of life and death altogether. Serenity is merely mental. Therefore, cultivate mental equipoise by gaining spiritual knowledge.
If you want to enjoy heaven on earth, go on purifying yourself by controlling the lower mind, the desires and cravings. All is bliss, all is joy, all is happiness then.
