By His Divine Grace A. C. Bhaktivedānta Swami Prabhupāda
It is advised in the Bhagavatam, “Don’t accept guru, don’t be father, don’t be mother, if you cannot stop death.” Either you don’t accept, or don’t become. Just like they want a guru (spiritual master) – so don’t accept a guru who cannot stop your death. And from guru’s side, it is advised, “Don’t become guru if you cannot stop the death of your disciple.”
So our Krishna consciousness movement is to stop death, live eternally with Krishna, go back to home, back to Godhead. This is our movement. So our guru gives us this opportunity – no more death.
Tyaktvā… After leaving this body, you don’t accept any more material body. And if you don’t accept material body, then there is no death. As soon as you are spiritual, you remain in spiritual body – there is no death. There is no birth also. Death is concomitant where birth is there. If the death is stopped, then there is no birth. And if there is no birth, there is no disease, there is no old age. This is the process.
So birth, death, old age, disease can be stopped only by Krishna consciousness. So if you don’t like to be Krishna conscious then what is the use of your becoming a disciple, and if the guru, if he cannot stop your death, birth and death, then what is the use of his becoming a guru?
