By their mercy, one can sharpen the sword of knowledge, and with the power of the Supreme Personality of Godhead's mercy one must then conquer the enemies mentioned above.

SB 7.15.45, Translation and Purport

As long as one has to accept a material body, with its different parts and paraphernalia, which are not fully under one's control, one must have the lotus feet of his superiors, namely his spiritual master and the spiritual master's predecessors. By their mercy, one can sharpen the sword of knowledge, and with the power of the Supreme Personality of Godhead's mercy one must then conquer the enemies mentioned above. In this way, the devotee should be able to merge into his own transcendental bliss, and then he may give up his body and resume his spiritual identity.

In Bhagavad-gītā (BG 4.9) the Lord says:

janma karma ca me divyam

evaṁ yo vetti tattvataḥ

tyaktvā dehaṁ punar janma

naiti mām eti so 'rjuna
