whose very nature is bliss
When the gopīs arrive in the night at the Yamunā, Kṛṣṇa tests them with philosophical arguments; his conclusion is that joy (sukha) is itself the criterion of right—his own blissful nature is the teaching.
सुखभावस् सुखाधारो मुकुन्दो मुदिताशयः ।अविक्रियः क्रियामूर्तिर् अध्यात्मस्वस्वरूपवान्॥
sukhabhāvas sukhādhāro mukundo muditāśayaḥ ·avikriyaḥ kriyāmūrtir adhyātmasvasvarūpavān
whose very nature is bliss
When the gopīs arrive in the night at the Yamunā, Kṛṣṇa tests them with philosophical arguments; his conclusion is that joy (sukha) is itself the criterion of right—his own blissful nature is the teaching.
the substratum of all happiness
At the Kurukṣetra pilgrimage, the Vṛndāvana gopīs and Mathurā queens reunite with Kṛṣṇa and declare him the sole foundation of all joy; they cannot release their embrace of his feet.
giver of liberation (mukti)
Devakī addresses the four-armed birth-form as 'Mukunda'—giver of liberation—and begs him to conceal this cosmic form lest Kaṃsa discover the truth and kill them all.
of joyful heart and disposition
Every day in Vṛndāvana, Kṛṣṇa and his cowherd friends go out driving calves, dancing, laughing, imitating forest animals; the text repeatedly describes his always-delighted heart.
the changeless, undergoing no modification
In the Sāṃkhya section of the Uddhava Gītā, Kṛṣṇa identifies himself as the supreme unchanging witness behind all the transformations of prakṛti.
embodiment of sacred action
The closing chapter of the Daśama Skandha describes Kṛṣṇa simultaneously fulfilling all duties—as husband to 16,108 queens, king, teacher, and warrior—without confusion or fatigue.
possessed of his own essential nature as the inner Self
In the haṃsa-avatāra episode, Kṛṣṇa teaches that his own essential nature (svasvarūpa) is pure undivided consciousness beyond name and form.
