Srimad Bhagavatam Canto 1 Chapter 8 Verse 12: "TRANSLATION
O foremost among the great thinkers [munis] [Śaunaka], seeing the glaring brahmāstra proceeding towards them, the Pāṇḍavas took up their five respective weapons.
The brahmāstras are finer than the nuclear weapons. Aśvatthāmā discharged the brahmāstra simply to kill the Pāṇḍavas, namely the five brothers headed by Mahārāja Yudhiṣṭhira and their only grandson, who was lying within the womb of Uttarā. Therefore the brahmāstra, more effective and finer than the atomic weapons, was not as blind as the atomic bombs. When the atomic bombs are discharged they do not discriminate between the target and others. Mainly the atomic bombs do harm to the innocent because there is no control. The brahmāstra is not like that. It marks out the target and proceeds accordingly without harming the innocent."
An original purport culled from the translation I randomly landed on based on my 'vedic research" on the Cayo-munio verse I learned over twenty years ago yet have never "completely forgotten". When one truly learns "eternal wisdom" it does not fade like so many other mundane topics/
