Adhyāya 179 — Bharadvāja’s Reductionist Inquiry into Jīva and Pañcabhūta Dissolution
इषुकारो नर: कश्चिदिषावासक्तमानस: । समीपेनापि गच्छन्तं राजानं नावबुद्धवान्
iṣukāro naraḥ kaścid iṣāv āsaktamānasaḥ | samīpenāpi gacchantaṃ rājānaṃ nāvabuddhavān |
ビーシュマは語った。「かつて矢を作る職人がいた。彼は矢作りに心を奪われ、王がすぐ近くを通っても気づかなかった。」この逸話は、一点に集める専心（エーカーグラター）の力を示すために引かれる。心が仕事に完全に収束すると、外の雑念は支配力を失う—ゆえにその者は模範によって“師”となる。

Educational Q&A
The verse teaches ekāgratā—single-pointed concentration. A mind fully absorbed in a chosen duty or practice becomes steady and undistracted, which is presented as a practical model for self-mastery and ethical discipline.
Bhishma narrates an example: an arrow-maker is so intent on crafting arrows that he fails to notice the king passing close by. This striking inattentiveness to external spectacle is used to highlight the depth of his focus.
