Trust in the Guru fully and wholeheartedly. Leave off all doubts. That is the only Sadhana. Guru is God. Guru is everything. He is your mother, father, well wisher, relative and true friend. Seeing all as Guru is the highest state and he who feels Him in every creature verily becomes Myself.
Surrender does not mean mere prostration and service to the Guru. It means complete surrender of everything, including the body and mind, with the conviction that the body belongs to the Guru and exists merely to serve Him.
There are innumerable saints in this world but "our father' (Guru) is the Father (Real Guru). Others might say many good things but we should never forget our Guru's words. http://www.babasaiofshirdi.org/
