Shloka 6
Book 10, Adhyāya 12: Aśvatthāmā’s Request for the Cakra and the Brahmaśiras Context
त॑ पुत्रो5प्पेक एवैनमन्वयाचदमर्षण: । ततः प्रोवाच पुत्राय नातिदहृष्टमना इव
tataḥ putro ’py eka evainam anvayācad amarṣaṇaḥ | tataḥ provāca putrāya nātidahṛṣṭamanā iva ||
毗湿摩波耶那说：随后，他那唯一的儿子也因无法忍受，向父亲哀求赐予同样的神兵。于是导师将那可怖的神矢之术传授给儿子；然而他心中并不甚欢喜——仿佛在暗示：即便传给亲子，将如此毁灭之力交付他人，也背负沉重的道义与凶险。

Educational Q&A
The verse underscores the ethical burden of transmitting destructive knowledge: even when a request is legitimate (from one’s own son), a responsible teacher may feel inner reluctance, aware that power without restraint can lead to adharma and catastrophe.
Aśvatthāmā, described as the teacher’s only son, cannot tolerate the situation and asks his father for the same powerful weapon. Droṇa instructs him in it, but appears not truly pleased, foreshadowing the dangerous consequences of such weapon-knowledge in the unfolding war.
