Ātma-saṃyama-dharma: One-pointedness of Mind and Senses (शुक–व्यास संवादः)
विधूमे सन्नमुसले वानप्रस्थप्रतिश्रये । काले प्राप्ते चरन् भैक्ष्यं कल्पते ब्रह्म भूयसे
vidhūme sannamusale vānaprasthapratiśraye | kāle prāpte caran bhaikṣyaṃ kalpate brahma bhūyase ||
毗耶娑说：当时机成熟时，那以乞食为生的出离者，应只在灶间无烟、杵声已息之际，前往林居者（vānaprastha）之所行乞。如此守持其律的行脚者，方堪证得梵（Brahman）之境。

Educational Q&A
A renunciant should beg in a way that minimizes burden and disturbance to householders/forest-dwellers—approaching only after cooking and pounding are finished—so that his livelihood remains pure, restrained, and aligned with the pursuit of Brahman.
Vyāsa lays down a practical rule of conduct for a mendicant: the sannyāsin should time his alms-round to a vānaprastha’s dwelling when there is no kitchen smoke and no sound of the pestle, indicating that the host’s work is done and the request will not cause disruption.
