"the weapon with which to conquer the enemy"

SB Canto 7

If one seriously desires to return home, back to Godhead, one must therefore become strong enough by pleasing the spiritual master, for thus one gets the weapon with which to conquer the enemy, and one also gets the grace of Kṛṣṇa.

SB 7.15.45, Purport:

A significant word here is acyuta-balaḥ. The spiritual master is certainly very merciful to his disciples, and consequently by satisfying him a devotee gets strength from the Supreme Personality of Godhead. Śrī Caitanya Mahāprabhu therefore says, guru-kṛṣṇa-prasāde pāya bhakti-latā-bīja: (CC Madhya 19.151) one must first please the spiritual master, and then one automatically pleases Kṛṣṇa and gets the strength with which to cross the ocean of nescience. If one seriously desires to return home, back to Godhead, one must therefore become strong enough by pleasing the spiritual master, for thus one gets the weapon with which to conquer the enemy, and one also gets the grace of Kṛṣṇa. Simply getting the weapon of jñāna is insufficient. One must sharpen the weapon by serving the spiritual master and adhering to his instructions. Then the candidate will get the mercy of the Supreme Personality of Godhead. In general warfare one must take help from his chariot and horses in order to conquer his enemy, and after conquering his enemies he may give up the chariot and its paraphernalia. Similarly, as long as one has a human body, one should fully use it to obtain the highest perfection of life, namely going back home, back to Godhead.
