Examine the Guru and his credentials, his ideals and practice, before accepting him. Even in My case, do not be attracted simply by stories of miracles. Do not jump to conclusions with closed eyes; watch, study and weigh. Never yield to any one unless you feel the inner satisfaction that you are on the right path. Do not run after Gurus who are themselves suffering from faulty vision and hose-holder's troubles; do not beg from people who are themselves beggars.
(From : Sai Veda, The Word of God, sayings of Bhagavan Sri Sathya Sai Baba)
