Shloka 3
Adhyāya 138: Vāyu’s Exempla on Brāhmaṇa-Prabhāva and a Cosmological Clarification
निरुद्धिग्नस्तु यो दद्यान्मासमेकं गवाह्विकम् | एकभक्तं तथाश्नीयाच्छुयतां तस्य यत् फलम्
niruddhignas tu yo dadyān māsam ekaṁ gavāhvikam | ekabhaktaṁ tathāśnīyāc chruyatāṁ tasya yat phalam |
マヘーシュヴァラは言った。「聞け。動揺と憂いを離れ、ひと月のあいだ日々、牛にその日々の糧（養い）を施し、自らは一日に一度のみ食する者に、いかなる報いが積もるか。かかる節ある布施と克己の果を聞け。」

Educational Q&A
The verse teaches that calm-minded charity (supporting/feeding a cow daily) combined with personal restraint (eating once a day) is a dharmic discipline whose merit yields a specific spiritual reward, to be described in the following lines.
Maheshvara is instructing the listener about a particular vow-like practice: for one month the practitioner provides daily sustenance connected with a cow and maintains an ekabhakta regimen; Maheshvara then invites the audience to hear the resulting ‘fruit’ (karmic/spiritual outcome).
