Bhagavān’s Avatāras, Their Protections (Poṣaṇa), and the Limits of Knowing Him
भूमे: सुरेतरवरूथविमर्दिताया: क्लेशव्ययाय कलया सितकृष्णकेश: । जात: करिष्यति जनानुपलक्ष्यमार्ग: कर्माणि चात्ममहिमोपनिबन्धनानि ॥ २६ ॥
bhūmeḥ suretara-varūtha-vimarditāyāḥ kleśa-vyayāya kalayā sita-kṛṣṇa-keśaḥ jātaḥ kariṣyati janānupalakṣya-mārgaḥ karmāṇi cātma-mahimopanibandhanāni
Lorsque la terre est accablée par la puissance guerrière de rois sans foi en Dieu, le Seigneur descend avec son expansion plénière afin d’alléger la détresse du monde. Il vient dans sa forme originelle, paré de beaux cheveux noirs; nul ne peut jauger sa manière d’agir, et pour déployer sa gloire transcendante il accomplit des œuvres extraordinaires.
This verse is especially describing the appearance of Lord Kṛṣṇa and His immediate expansion, Lord Baladeva. Both Lord Kṛṣṇa and Lord Baladeva are one Supreme Personality of Godhead. The Lord is omnipotent, and He expands Himself in innumerable forms and energies, and the whole unit is known as the one Supreme Brahman. Such extensions of the Lord are divided into two divisions, namely personal and differential. The personal expansions are called the viṣṇu-tattvas, and the differential expansions are called the jīva-tattvas. And in such expansional activity, Lord Baladeva is the first personal expansion of Kṛṣṇa, the Supreme Personality of Godhead.
It states that when the earth is oppressed by ungodly forces, the Lord appears (in a partial expansion) to remove her distress, and His extraordinary deeds become famous accounts that proclaim His divine glory.
Śukadeva is indicating the Lord’s appearance with distinctive features associated with His incarnations—classically understood as pointing to divine descents connected with white and black complexions—while emphasizing that the Lord’s advent is for restoring dharma and relieving the earth’s burden.
By trusting that the Lord intervenes to protect dharma, and by regularly hearing and sharing His līlās—since these narrations are meant to awaken devotion through remembrance of His greatness.
