Matsya Purana — Navagraha Sacrifice for Planetary Pacification and Prosperity
अवश्यानि वशी कुर्यात् सर्वशत्रुबलान्यपि अमित्राण्यपि मित्राणि होमो ऽयं पापनाशनः //
avaśyāni vaśī kuryāt sarvaśatrubalānyapi amitrāṇyapi mitrāṇi homo 'yaṃ pāpanāśanaḥ //
By this rite of homa, one can bring even the inevitable under control and subdue the powers of all enemies; even foes become friends. This homa is a destroyer of sin.
This verse does not discuss pralaya directly; it emphasizes ritual efficacy—homa as a pāpanāśana (sin-destroyer) that restores order and auspiciousness within worldly life.
It supports the dharmic ideal that rulers and householders maintain social and personal harmony through prescribed rites: homa is presented as a means to remove moral faults, strengthen auspicious power, and even convert hostility into alliance—useful for both governance and domestic stability.
Ritually, it highlights homa as a purification and protection practice (pāpanāśana) often performed before major undertakings; by extension, such purification rites are commonly paired with Vastu/temple activities to secure auspicious outcomes.
