avatīrṇo ’si me gṛhe
cikīrṣur bhagavān jñānaṁ
When the Lord appeared before Kardama Muni after his mature yoga practice, He promised that He would become Kardama’s son. He descended as the son of Kardama Muni in order to fulfill that promise. Another purpose of His appearance is cikīrṣur bhagavān jñānam, to distribute knowledge. Therefore He is called bhaktānāṁ māna-vardhanaḥ, “He who increases the honor of His devotees.” By distributing Sāṅkhya He would increase the honor of the devotees; therefore Sāṅkhya philosophy is not dry mental speculation. Sāṅkhya philosophy means devotional service. How could the honor of the devotees be increased unless Sāṅkhya were meant for devotional service? Devotees are not interested in speculative knowledge; therefore the Sāṅkhya enunciated by Kapila Muni is meant to establish one firmly in devotional service. Real knowledge and real liberation is to surrender unto the Supreme Personality of Godhead and engage in devotional service.
