Adhyāya 51: Kṛṣṇa’s Leave-Taking and Departure for Dvārakā (द्वारकागमनानुमति)
ध्यानयोगमुपागम्य प्रसन्नमतय: सदा । सुखोपचयमव्यक्तं प्रविशन्त्यात्मवित्तमा:,जो ध्यानयोगका आश्रय लेकर सदा प्रसन्नचित्त रहते हैं, वे आत्मवेत्ताओंमें श्रेष्ठ पुरुष सुखकी राशिभूत अव्यक्त परमात्मामें प्रवेश करते हैं
dhyānayogam upāgamya prasannamatayaḥ sadā | sukhopacayam avyaktaṃ praviśanty ātmavittamāḥ ||
Having taken refuge in the discipline of meditation (dhyāna-yoga), those whose minds remain ever serene—foremost among the knowers of the Self—enter the Unmanifest (avyakta), a very treasury of bliss.
वायुदेव उवाच
Steady serenity born of dhyāna-yoga leads the foremost self-knowers beyond the manifest world into the avyakta—the unmanifest, blissful ultimate reality. The ethical emphasis is on inner clarity and sustained contemplative discipline rather than external achievement.
Vāyudeva is instructing about the destiny of accomplished meditators: those who consistently maintain a tranquil mind through meditation attain entry into the unmanifest supreme principle described as a repository of bliss.
