Why do we bow down to a guru, and how does it help remove pride?
Bowing dissolves pride
In Tibet's tradition a student bows 1000 times toward the guru's hut, whether or not the guru sees. The bowing is done so that your pride dissolves into the ground. Only then are you called the best disciple.
The prostration is made so that your pride dissolves into the ground; only then will you be called a true disciple.
