tataḥ katipayāhobhir
jagāma deva-devasya
śeṣasya caraṇāntikam
tataḥ—thereafter; katipaya-ahobhiḥ—within a few days; vidyayā—by the spiritual mantra; iddha-manaḥ-gatiḥ—the course of his mind being enlightened; jagāma—went; deva-devasya—of the master of all other lords or demigods; śeṣasya—Lord Śeṣa; caraṇa-antikam—to the shelter of the lotus feet.
Thereafter, within a very few days, by the influence of the mantra that Citraketu had practiced, his mind became increasingly enlightened in spiritual progress, and he attained shelter at the lotus feet of Anantadeva.
A devotee’s ultimate achievement is to take shelter of the lotus feet of the Lord in any one of the planets in the spiritual sky. As a result of rigid execution of devotional service, a devotee receives all material opulences if these are required; otherwise, the devotee is not interested in material opulences, nor does the Supreme Lord award them. When a devotee is actually engaged in the devotional service of the Lord, his apparently material opulences are not material; they are all spiritual. For example, if a devotee spends money to construct a beautiful and costly temple, the construction is not material but spiritual (nirbandhaḥ kṛṣṇa-sambandhe yuktaṁ vairāgyam ucyate). A devotee’s mind is never diverted to the material side of the temple. The bricks, stone and wood used in the construction of the temple are spiritual, just as the Deity, although made of stone, is not stone but the Supreme Personality of Godhead Himself. The more one advances in spiritual consciousness, the more he can understand the elements of devotional service. Nothing in devotional service is material; everything is spiritual. Consequently a devotee is awarded so-called material opulence for spiritual advancement. This opulence is an aid to help the devotee advance toward the spiritual kingdom. Thus Mahārāja Citraketu remained in material opulence as a vidyādhara-pati, master of the Vidyādharas, and by executing devotional service he became perfect within a very few days and returned home, back to Godhead, taking shelter of the lotus feet of Lord Śeṣa, Ananta.
A karmī’s material opulence and a devotee’s material opulence are not on the same level. Śrīla Madhvācārya comments in this way:
anyāntaryāmiṇaṁ viṣṇum
bhaved yogyatayā tasya
padaṁ prāpnuyān naraḥ
By worshiping Lord Viṣṇu one can get whatever he desires, but a pure devotee never asks Lord Viṣṇu for any material profit. Instead he serves Lord Viṣṇu without material desires and is therefore ultimately transferred to the spiritual kingdom. In this regard, Śrīla Vīrarāghava Ācārya comments, yatheṣṭa-gatir ity arthaḥ: by worshiping Viṣṇu, a devotee can get whatever he likes. Mahārāja Citraketu wanted only to return home, back to Godhead, and therefore he achieved success in that way.
