Mahabharata — Shanti Parva, Shloka 23
Prahlāda–Indra Saṃvāda: Kartṛtva (Agency) and Svabhāva (Nature) in the Causation of Karma
आहारनियमं चैव देशे काले च सात्विकम् । तत् परीक्ष्यानुवर्तेत तत्प्रवृत्त्यनुपूर्वकम्
āhāra-niyamaṃ caiva deśe kāle ca sāttvikam | tat parīkṣyānuvarteta tat-pravṛtty-anupūrvakam ||
毗湿摩说道：“当立饮食之戒，使其具萨埵之清净，并随地域与时令而相宜。审察此饮食——其利与其弊——然后循序渐进而奉行，只取能资助修行与成就之物。”

Educational Q&A
Regulate one’s diet with discernment: choose sāttvika food appropriate to place and season, evaluate its benefits and drawbacks, and adopt it gradually in a way that supports spiritual practice and yogic progress.
In the Śānti Parva’s instruction on right conduct and inner discipline, Bhīṣma advises the listener on practical ascetic guidelines—here, how to manage food intake as part of a broader regimen aimed at self-mastery and spiritual attainment.
