Chapter 7, Verse 19
Part of 7: Jñāna Vijñāna Yog — ज्ञानविज्ञानयोगबहूनां जन्मनामन्ते ज्ञानवान्मां प्रपद्यते। वासुदेवः सर्वमिति स महात्मा सुदुर्लभः॥
bahūnāṁ janmanām ante jñānavān māṁ prapadyate vāsudevaḥ sarvam iti sa mahātmā su-durlabhaḥ
At the end of many births, the wise man comes to Me, realizing that all this is Vaasudeva (the innermost Self); such a great soul (Mahatma) is very hard to find.
Vaasudeva is a name of Lord Krishna as He is the son of Vasudeva. He is the allpervading Brahman. The aspirant gradually evolves through Yogic practices, selfless service, devotion and constant meditation in many births and ultimately attains the inner Self. He realises that all is Vaasudeva. It is very difficult to find such a great soul, who has attained to perfection. No one is eal to him. That is the reason why the Lord has said? One in a thousand perchance strives for perfection even among those successful strivers, only one perchance knows Me in essence. (Cf. VII.3.)
