Sanātana's inquiry was therefore an intelligent one. "What is the position of the living entities?" he asked. "Why are they always undergoing these three kinds of miseries?" Sanātana had admitted his weakness. Although he was known by the masses of people as a greatly learned man (and actually he was a highly learned Sanskrit scholar), and although he accepted this designation, he did not actually know what his constitutional position really was and just why he was subjected to the threefold miseries.
Approaching a spiritual master is not just a fashion but is a necessity for one who is seriously conscious of the material miseries and who wants to be free of them. It is the duty of such a person to approach a spiritual master. In this regard, we should note similar circumstances in Bhagavad-gītā. When Arjuna was perplexed by so many problems involving whether to fight or not, he accepted Lord Kṛṣṇa as his spiritual master. It was also a case of the supreme spiritual master instructing Arjuna about the constitutional position of the living entity.
In Bhagavad-gītā we are informed that the constitutional nature of the individual entity is spirit soul. He is not matter. As spirit soul, he is part and parcel of the supreme soul, the Absolute Truth, the Personality of Godhead. We also learn that it is the duty of the spirit soul to surrender, for only then can he be happy. The last instruction of Bhagavad-gītā is that the spirit soul surrender completely unto the supreme soul, Kṛṣṇa, and in that way realize happiness.
