The real vidvān is one who tries to understand his own position within this material world. For example, when Sanātana Gosvāmī submitted to the lotus feet of Śrī Caitanya Mahāprabhu, his first question was 'ke āmi', 'kene āmāya jāre tāpa-traya'. In other words, he wanted to know his constitutional position and why he was suffering from the threefold miseries of material existence. This is the process of education. If one does not ask, "Who am I? What is the goal of my life?" but instead follows the same animal propensities as cats and dogs, what is the use of his education? As discussed in the previous verse, a living being is entrapped by his fruitive activities, exactly like a silkworm trapped in its own cocoon. Foolish persons are generally encaged by their fruitive actions (karma) because of a strong desire to enjoy this material world. Such attracted persons become involved in society, community and nation and waste their time, not having profited from having obtained human forms. Especially in this age, Kali-yuga, great leaders, politicians, philosophers and scientists are all engaged in foolish activities, thinking, "This is mine, and this is yours."
