SB 1.1 - Question 3 - Why did Kṛṣṇa appear in this world?

(Q3) (1.1.12) The sages asked Sūta to explain for what purpose the Personality of Godhead appeared in the womb of Devakī as the son of Vasudeva. Persons who are servitors of the Absolute Truth are called sātvatas, and the Lord who protects such pure devotees is called sātvatām patiḥ. Vasudeva is the symbol of the transcendental position wherein the appearance of the Supreme Lord takes place. The Lord appears to broadcast His wonderful qualities, not to relieve the burden of the earth. He made His appearance for the liberation and material prosperity of all beings. The sages were eager to learn about the Lord and His incarnations. They asked Sūta to explain the teachings of the ācāryas, for one is uplifted both by speaking them and by hearing them. The conditions for hearing the transcendental message of the Lord are that the audience must be very sincere and eager to hear, and the speaker must be in the line of disciplic succession from the recognized ācārya. Sūta was in the line of Śrīla Vyāsa and the sages of Naimiṣāraṇya were all sincere souls who were anxious to learn the truth.
