Adhyāya 138: Vāyu’s Exempla on Brāhmaṇa-Prabhāva and a Cosmological Clarification
तस्य तत्र चतुर्भागो यो ददाति गवाद्विकम्
tasya tatra caturbhāgo yo dadāti gavādvikam
या विषयात जो मनुष्य नित्य गायीला अन्न देतो, त्याला सतत केली जाणाऱ्या गोसेवेच्या फळातील एक चतुर्थांश पुण्य प्राप्त होते.
महेश्वर उवाच
Regularly feeding and serving cows is presented as a dharmic act that yields spiritual merit; even the specific act of giving food to a cow grants a defined share—one quarter—of the merit associated with ongoing cow-service, emphasizing disciplined, compassionate giving.
Maheśvara is explaining the religious efficacy of honoring cows: cows are described as powerful and boon-giving, and he quantifies the merit gained by a person who habitually feeds cows, linking the practice to the attainment of desired fruits of action.
