अन्नदानफलं (Anna-dāna-phala) / The Fruit of Food-Giving
वैशाखमासे द्वादश्यां पूजयन् मधुसूदनम् । अग्निष्टोममवाप्रोति सोमलोकं च गच्छति
vaiśākhamāse dvādaśyāṃ pūjayan madhusūdanam | agniṣṭomam avāpnoti somalokaṃ ca gacchati ||
毗湿摩说道：在毗舍迦月（Vaiśākha）的十二日（Dvādaśī），若有人以斋戒持愿而礼拜摩度苏陀那（Madhusūdana，毗湿奴），便得与阿耆尼什多摩（Agniṣṭoma）祭同等之功德，并往苏摩之界。

Educational Q&A
The verse teaches that sincere devotional worship of Vishnu (Madhusūdana), performed on an auspicious tithi with self-restraint such as fasting, can yield merit comparable to a major Vedic sacrifice (Agniṣṭoma), indicating an inclusive dharmic path where inner devotion and disciplined observance can substitute for expensive ritual performance.
In Bhishma’s instruction on dharma, he describes the spiritual fruit of a specific observance: worshipping Madhusūdana on Vaiśākha Dvādaśī. He states the promised result—Agniṣṭoma-like merit and ascent to Somaloka—thereby recommending the vrata as a powerful religious practice.
