सेव्यं तु ब्रह्म षट््कर्म गृहस्थेन मनीषिणा । कृतकृत्यस्य चारण्ये वासो विप्रस्य शस्यते,मनीषी ब्राह्मण यदि गृहस्थ हो तो उसके लिये वेदोंका अभ्यास और यजन-याजन आदि छ:कर्म ही सेवन करने योग्य हैं। गृहस्थ आश्रमका उद्देश्य पूर्ण कर लेनेपर ब्राह्मणके लिये (वानप्रस्थी होकर) वनमें निवास करना उत्तम माना गया है
sevyam tu brahma ṣaṭ-karma gṛhasthena manīṣiṇā | kṛtakṛtyasya cāraṇye vāso viprasya śasyate ||
Bhīṣma said: For a discerning householder, what should be pursued is sacred Vedic learning together with the six duties—such as performing sacrifice and officiating for others. And when the aims of the householder stage have been fulfilled, it is praised for a brāhmaṇa to dwell in the forest, adopting the life of withdrawal and discipline.
भीष्म उवाच
A wise brāhmaṇa should, while living as a householder, devote himself to Vedic learning and the six prescribed duties; after fulfilling household obligations, he is commended to withdraw to forest life (vanaprastha) as a disciplined next stage.
In Bhīṣma’s instruction on dharma in the Śānti Parva, he outlines the proper conduct across life-stages, specifically prescribing the householder’s religious responsibilities and then recommending forest-dwelling once those responsibilities are completed.
