Shloka 243
Brahmopadeśa: Adhipatitva-kathana, Dharma-lakṣaṇa, and Kṣetra–Kṣetrajña Viveka
Book 14, Chapter 43
बुद्धिह्हि व्यवसायेन लक्ष्यते नात्र संशय: । चिन्तन मनका और निश्चय बुद्धिका लक्षण है; क्योंकि मनुष्य इस जगतमें मनके द्वारा चिन्तन की हुई वस्तुओंका बुद्धिसे ही निश्चय करते हैं
buddhir hi vyavasāyena lakṣyate nātra saṁśayaḥ |
风神伐由说道：“智（buddhi）以其果断之力而为人所识；此中毫无疑惑。心（manas）可以驰骋于种种思虑与可能，但唯有智才能裁定并安立当取之事。故而，确定与坚决，正是识别智的显著标志。”
वायुदेव उवाच
Educational Q&A
The verse defines buddhi (intellect) by vyavasāya—firm determination and decisive ascertainment. Thoughts may arise in the mind, but the intellect is known by its capacity to conclude, choose, and settle on a course with clarity.
Vāyudeva is speaking in a didactic context, offering a definition of the inner faculties. He distinguishes the mind’s role in thinking from the intellect’s role in arriving at certainty, emphasizing discernment as a moral and practical guide.
