Śrāddha-kalpa: Dāna-phala-nirdeśa
Gifts in Śrāddha and Their Fruits
श्राद्धेष्वेतानि यो दद्यादश्वमेधफलं लभेत् / श्राद्धकाले गुणवति विप्रे वै समुपस्थिते
śrāddheṣvetāni yo dadyādaśvamedhaphalaṃ labhet / śrāddhakāle guṇavati vipre vai samupasthite
Whoever gives these offerings in the śrāddha attains the fruit of the Aśvamedha, especially when, at the time of śrāddha, a virtuous brāhmaṇa is duly present.
