Anuśāsana-parva 108
न भूज्जीत च मेधावी तथायुर्विन्दते महत् । राजन! बुद्धिमान् पुरुष सायंकालमें गोधूलिकी वेलामें न तो सोये, न विद्या पढ़े और न भोजन ही करे। ऐसा करनेसे वह बड़ी आयुको प्राप्त होता है
na bhuñjīta ca medhāvī tathāyur vindate mahat | rājan! buddhimān puruṣaḥ sāyaṅkāle godhūlikī-velāyāṃ na tu śete, na vidyāṃ paṭhati, na bhojanaṃ hi karoti | evaṃ kṛtvā sa mahad āyuḥ prāpnoti |
ビーシュマは言った。「王よ、分別ある者は夕べの『牛塵の刻』（ゴードゥーリー、黄昏）に、眠ってはならず、学問に励んでもならず、また食を取ってもならぬ。そのように慎みを守る者は、大いなる長寿を得ると言われる。」

Educational Q&A
Bhishma teaches disciplined conduct at twilight (godhūlikā-velā): avoid eating, sleeping, and even study at that liminal time; such restraint is presented as supportive of health and long life.
In Anushasana Parva, Bhishma instructs the king on dharma and proper conduct (ācāra). Here he gives a practical rule of daily regimen, linking twilight discipline with the ethical ideal of self-control and the promised fruit of longevity.
