SB Canto 6

If a devotee, after being initiated, adheres rigidly to the instructions of the spiritual master, he is naturally endowed with the material opulences of vidyādhara-adhipatyam and similar posts as by-products. A devotee need not practice yoga, karma or jñāna to achieve a successful result. Devotional service alone is competent to award a devotee all material power. A pure devotee, however, is never attached to material power, although he gets it very easily without personal endeavor. Citraketu received this side benefit of his devotional service, which he rigidly performed in accordance with the instructions of Nārada.
