Śrī brahma-saṁhitā 5.26

Although the object of meditation is fully transcendental, yet owing to her nature which is permeated with the quality of active mundane hankering, Māyā, the nonspiritual potency of Kṛṣṇa, embodying the principles of mixed sattva, rajas, and tamas, in the forms of Durgā, and other nonspiritual powers, meditated on the Supreme Lord Kṛṣṇa as the object of their worship. So long as there is any trace of mundane desire in one’s heart, it is the object of worship of Māyādevī (Durgā) who has to be worshiped by such a person; nevertheless the fulfillment of one’s heart’s desire results from the worship of the object of worship of Māyādevī, and not from the worship of Māyādevī herself. This is in accordance with the śloka, akāmaḥ sarva-kāmo vā mokṣa-kāma udāra-dhiḥ / tīvreṇa bhakti-yogena yajeta puruṣaṁ param [SB 2.3.10]. The meaning of this śloka of the Bhāgavatam is that though other gods, as distinct manifestations of the Supreme Lord, are bestowers of sundry specific boons, yet a sensible person should worship the all powerful Supreme Lord, giver of all good, with unalloyed devotion, without worshiping those mundane gift-giving deities. Accordingly, Brahmā meditated upon Kṛṣṇa in Goloka, the object of the worship, from a distance, of Māyādevī. True devotion is unalloyed devotional activity free from all mundane desire. The devotion of Brahmā, etc., is not unmixed devotion. But there is a stage of unmixed predilection even in devotion for the attainment of one’s selfish desire. This has been fully described in the concluding five ślokas of this work. That is the easiest method of divine service, prior to the attainment of self-realization, by fallen souls.
