Matsya Purana — Characteristics of Dvāpara and Kali Yugas
शूद्राणां मन्त्रयोनिस्तु सम्बन्धो ब्राह्मणैः सह भवतीह कलौ तस्मिञ् छयनासनभोजनैः //
śūdrāṇāṃ mantrayonistu sambandho brāhmaṇaiḥ saha bhavatīha kalau tasmiñ chayanāsanabhojanaiḥ //
In that Kali age, a Śūdra’s claim to mantra-initiation (as a ‘source of mantra’) and close association with Brāhmaṇas will come to be—sharing beds, seats, and food together.
This verse is not about pralaya; it describes Kali-yuga social conditions—especially changing boundaries of association and ritual status between varṇas.
It functions as a Kali-yuga diagnostic: a king or householder is urged (by implication) to uphold dharma and social-ritual discipline, since commensality and intimacy across traditional boundaries are presented here as markers of moral and ritual decline.
The ritual point is mantra-related eligibility and commensality rules (eating/sitting/reclining together), which in Dharma literature affect purity norms and who may participate in certain rites.
