Faith can grow only from the root of inquiry. Faith is made firmer by inquiry. Therefore steady inquiry is essential; do not be led by others; awaken your reason, amass your own experience; and decide for yourself, your own path. Then only can you get joy in treading it; if you are forced to take a path by others or persuaded into it by some one else, then, when the first obstacle turns up, you will get dispirited and turn back.
(From : Sai Veda, The Word of God, sayings of Bhagavan Sri Sathya Sai Baba)
