FAQs
It implies a single supreme reality expressed through different divine functions: preservation (Hari), dissolution/transformative power (Hara), and creation (Prajāpati), whose prominence varies with the guṇa-character of a kalpa.
No specific practice is taught directly; the verse provides a doctrinal frame used in Kurma Purana’s yoga-theology—guiding devotees to contemplate Īśvara’s one power appearing as different deities according to cosmic conditions (guṇa and kalpa).
It presents a synthesis: Hari and Hara are not rivals but alternate emphases within different guṇa-dominated cosmic cycles, supporting the Kurma Purana’s non-sectarian Shaiva–Vaishnava unity.
