Matsya Purana — The Origin of Yajña in Tretā Yuga and the Debate on Animal Sacrifice vs. Non-...
तस्मान्न हिंसा यज्ञे स्याद् यदुक्तमृषिभिः पुरा ऋषिकोटिसहस्राणि स्वैस्तपोभिर्दिवं गताः //
tasmānna hiṃsā yajñe syād yaduktamṛṣibhiḥ purā ṛṣikoṭisahasrāṇi svaistapobhirdivaṃ gatāḥ //
Therefore, in a yajña there should be no violence—so it was proclaimed by the sages of old; for countless crores and thousands of ṛṣis attained heaven through their own tapas (austerity).
This verse does not address pralaya directly; it teaches an ethical rule for religious practice—yajña should be free from violence, and spiritual attainment is praised through tapas rather than injury.
It frames dharma as restraint: a king or householder should support righteous rites that avoid harm, and should value self-discipline (tapas) as a legitimate path to merit rather than relying on violent ritual acts.
The ritual takeaway is explicit: in yajña, hiṃsā (injury) is to be avoided; the verse reinforces a yajña-vidhi principle that purity and merit can be achieved through austerity and disciplined observance rather than violence.
