“So long as you still possess other weapons, if—without a true life‑and‑death necessity—you carelessly release this unfailing missile, then, beyond doubt, it will recoil and fall back upon you yourself.”
कर्ण उवाच
Extraordinary power must be governed by restraint and proper occasion; using an infallible weapon in carelessness or without true necessity invites self-harm, showing that pramāda (heedlessness) turns strength into danger.
Karna is being cautioned about the conditions for deploying an 'unfailing' missile: as long as other weapons remain and there is no extreme peril, releasing it rashly will not strike the intended enemy but will rebound upon Karna himself.
