SB 10.14.3 — Those who, even while remaining situated in their established social positions, throw away the process of speculative knowledge and with their body, words and mind offer all respects to descriptions of Your personality and activities, dedicating their lives to these narrations, which are vibrated by You personally and by Your pure devotees, certainly conquer Your Lordship, although You are otherwise unconquerable by anyone within the three worlds.

SB 10.14.4 — My dear Lord, devotional service unto You is the best path for self-realization. If someone gives up that path and engages in the cultivation of speculative knowledge, he will simply undergo a troublesome process and will not achieve his desired result. As a person who beats an empty husk of wheat cannot get grain, one who simply speculates cannot achieve self-realization. His only gain is trouble.
