यज्ञप्रवर्तनम् (Yajña-pravartana) — The Institution/Commencement of Sacrifice in Dvāpara
युगेयुगे तु हीयन्ते त्रित्रिपादास्तु सिद्धयः / युगस्वभावात्संध्यासु तिष्ठन्तीह तु यादृशः
yugeyuge tu hīyante tritripādāstu siddhayaḥ / yugasvabhāvātsaṃdhyāsu tiṣṭhantīha tu yādṛśaḥ
From age to age the siddhis decline; even those founded on three ‘quarters’ diminish. By the very nature of each yuga, in the sandhyā periods they remain here just as they are.
