Suvarṇa-dāna: Kārttikeya’s Origin and the Defeat of Tāraka (सुवर्णदान-प्रसङ्गे कार्त्तिकेय-उत्पत्ति तथा तारकवधः)

আমি বললাম—দেবী! শুভাননে! তুমি লোভ ও কামনা ত্যাগ করেছ। নিষ্কাম তপস্যায় আমি প্রসন্ন; অতএব তোমাকে অমরত্বের বর দিচ্ছি।
भीष्म उवाच
Austerity becomes ethically and spiritually potent when it is free from greed and desire for personal gain; such selfless discipline (niṣkāma tapas) is praised as worthy of divine grace and extraordinary reward.
Bhishma, speaking in the Anushasana Parva, recounts a moment where a divine woman is commended for performing austerities without greed or wish-fulfillment motives, and he (or the narrator within the cited episode) grants her the boon of immortality as a response to that purity of intent.
