Dear Sonamdarhey,
Thank you very much for posting this video of Dzongsar Khyentse Rinpoche.
I find that what he says makes a lot of sense and is very true.
A disciple looks for a Guru because they “need” help.
And a true Guru, will teach according to what the disciple need, not to cater to what he/she wants. This is because if the Guru teaches according to the needs instead of the wants of the disciple, he/she is purely thinking about how to benefit his/her disciples and there are no hidden agenda.
The disciples must also understand that the Guru, if he/she is a real one, will not be afraid to risk being hated or despised when prescribing his cure, which is in the way he teaches and train the disciples.
Due to our own ego, and impure mind, we do not like to listen to the truth about ourselves. Because very often, the truth is hurtful and it shows us how ugly we can be. But if we do not have a Guru to point out to us our flaws, and not willing to accept and start transforming, then the disciples will never progress.
Hence the trust between the Guru and Disciple is very important. The disciple if really seeking for enlightenment should trust the Guru and go all the way without any personal agenda and be consistent whether in the presence of the Guru or not. This in turn will make the Guru gain trust towards the disciple, seeing his/her integrity and consistency will only mean that he/she have surrendered and is really following the Guru's advise.
