Im Tretā-Yuga wird diese Mantra-Disziplin um ein Viertel vermindert gelehrt; im Dvāpara soll sie zur Hälfte ausgeführt werden; und im Kali-Yuga nur zu einem Viertel.
Unspecified (didactic narration within the tīrtha episode)
Type: kshetra
Listener: Dvijottama
Scene: A symbolic depiction of four yugas as diminishing pillars or steps, with a sādhaka’s practice measure reducing accordingly—yet the sacred flame remains steady, signifying preserved essence.
The Purāṇic tradition calibrates practice to the capacities of each age, emphasizing realism without abandoning discipline.
The yuga-teaching is embedded in a tīrtha narrative of Nāgarakhaṇḍa; the exact pīṭha is specified nearby (later verses mention Cित्रेश्वर-pīṭha).
A yuga-based measure for mantra-sādhana: 3/4 in Tretā, 1/2 in Dvāpara, 1/4 in Kali.
