Forest-Stage Discipline and Austerity
तस्मिन्नहनि मन्यन्ते परिहार्य हि मैथुनम् । शुचिना तु सदा श्राद्धं भोक्तव्यं खेचरोत्तम
tasminnahani manyante parihārya hi maithunam | śucinā tu sadā śrāddhaṃ bhoktavyaṃ khecarottama ||
“在那一日，人们认为房事确应避绝。并且，唯有经由沐浴等而得清净者，方可常常受用祭祖供食（śrāddha）。噫，诸天行者之最胜者！”

The verse teaches ritual discipline on the day of śrāddha: abstain from sexual intercourse and maintain purity; the śrāddha meal should be taken only after purification, reflecting reverence for the ancestors and the sanctity of the rite.
A divine messenger (Devadūta) is speaking, laying down conduct connected with śrāddha observance—specifically, the household’s restraint and the Brahmin’s purified participation in the śrāddha meal—framed as authoritative guidance on proper ritual behavior.
