Srimad-Bhagavatam: Canto 12 - Chapter 1 - Verse 6

Sanskrit:

श्रीभगवानुवाचनैवेच्छत्याशिष: क्‍वापि ब्रह्मर्षिर्मोक्षमप्युत ।भक्तिं परां भगवति लब्धवान् पुरुषेऽव्यये ॥ ६ ॥

ITRANS:

śrī-bhagavān uvācanaivecchaty āśiṣaḥ kvāpibrahmarṣir mokṣam apy utabhaktiṁ parāṁ bhagavatilabdhavān puruṣe ’vyaye

Translation:

Lord Śiva replied: Surely this saintly brāhmaṇa does not desire any benediction, not even liberation itself, for he has attained pure devotional service unto the inexhaustible Personality of Godhead.

Purport:

The words naivecchaty āśiṣaḥ kvāpi indicate that Mārkaṇḍeya Ṛṣi was uninterested in any reward available on any planet within the universe. Nor did he want liberation, for he had achieved the Supreme Lord Himself.
