Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 18

Sanskrit:

अथापि काले स्वजनाभिगुप्तयेबिभर्षि सत्त्वं खलनिग्रहाय च ।स्वलीलया वेदपथं सनातनंवर्णाश्रमात्मा पुरुष: परो भवान् ॥ १८ ॥

ITRANS:

athāpi kāle sva-janābhiguptayebibharṣi sattvaṁ khala-nigrahāya casva-līlayā veda-pathaṁ sanātanaṁvarṇāśramātmā puruṣaḥ paro bhavān

Translation:

Nonetheless, at suitable times You assume the pure mode of goodness to protect Your devotees and punish the wicked. Thus You, the Soul of the varṇāśrama social order, the Supreme Personality of Godhead, maintain the eternal path of the Vedas by enjoying Your pleasure pastimes.

Purport:

This verse describes the Lord’s enlightening people in general (jana-saṅgraha) and His imitation of worldly behavior. Because the Personality of Godhead remains always perfect, the body He manifests when He comes to this world is not touched by material goodness; rather, it is a manifestation of the pure goodness known as viśuddha-sattva, the same spiritual substance that constitutes His original form.
