The world is an illusion and all is BRAHMAN (supreme being) only for one who has reached the ultimate goal; but, until realization dawns, one has to wait patiently, hoping and preparing. The growing baby cannot be fed on adult food; you have to adjust the food to the needs and capabilities of the child. You should not over do or avoid doing anything. Both lead to disease and ruin health.
(From : Sai Veda, The Word of God, sayings of Bhagavan Sri Sathya Sai Baba)
