Who is a Guru and who is a disciple?"

Aum Sai Ram.

"A Guru is the Match Box and the disciple is the Match Stick, who catches fire, by striking itself on it. It can catch fire, only if ain't damp enough with self-pride or egotistic."

"Then whose is the hand, which holds them both?"

"The hands of fate, of course..."

The disciple seldom gets to find His Guru. It is the Guru, who ultimately finds Him and shows him the truth. Alas! These days, majority are just business partnerships.
