毗湿摩说道：因此，婆罗多族中最卓越者啊，应当不断施灯。为诸天与祖灵而供，此施据说有益于眼目，并能增长自身内在的光辉，主上啊。

Educational Q&A
Bhishma teaches that regular dīpa-dāna (donating/lighting lamps) as an offering to the gods and ancestors is a meritorious practice, praised for bringing clarity and strengthening one’s vision and inner radiance.
In the Anuśāsana Parva’s instruction section, Bhishma continues advising Yudhiṣṭhira on dharma and gifts (dāna), here recommending continual lamp-offering for deities and Pitṛs and stating its beneficial result.
