आत्मानं ब्रह्म निर्वाणं प्रत्यस्तमितविग्रहम् । अवबोधरसैकात्म्यमानन्दमनुसन्ततम् ॥ ८ ॥ अव्यवच्छिन्नयोगाग्निदग्धकर्ममलाशय: । स्वरूपमवरुन्धानो नात्मनोऽन्यं तदैक्षत ॥ ९ ॥
ātmānaṁ brahma-nirvāṇaṁ pratyastamita-vigraham avabodha-rasaikātmyam ānandam anusantatam
By expansion of his knowledge of the Supreme Brahman, he had already attained liberation from the bondage of the body. This liberation is known as nirvāṇa. He was situated in transcendental bliss, and he continued always in that blissful existence, which expanded more and more. This was possible for him by continual practice of bhakti-yoga, which is compared to fire because it burns away all dirty, material things. He was always situated in his constitutional position of self-realization, and he could not see anything else but the Supreme Lord and himself engaged in discharging devotional service.
These two verses explain the verse in the Bhagavad-gītā (18.54) :
This verse describes nirvāṇa as realizing the self as Brahman—where material identity dissolves and one abides in continuous awareness and bliss.
Because he entered deep spiritual absorption in which bodily identification and material designations cease, revealing the self’s spiritual nature.
Cultivate steady sādhana—hearing, chanting, and meditation—so the mind becomes less ruled by bodily identity and more anchored in spiritual remembrance.
