Matsyapurana 101.24

101.24

vratānte vipramithunaṃ pūjyaṃ dhenutrayānvitam
vṛkṣaṃ hiraṇmayaṃ dadyāt so'śvamedhaphalaṃ labhet
etat kīrtivrataṃ nāma bhūtikīrtiphalapradam //

One who takes his meal once a day, in silence, bereft of vice for a full year and salutes the peepul tree, the sun and the Ganges together, and at the end of the ordinance adores the Brâhmaṇa with his consort, having given them a golden tree with three cows, attains the benefit of Aśvamedha sacrifice. This is called the (13) Kîrti-Vrata—the giver of every fame and prosperity.—23-24.
