अग्निनिचयः (Agninichaya) / The Accumulation of Sacred Fire & the Classification of Pitṛs by Time-Order
चातुर्वर्ण्यं हि देवानां ते चाप्येकत्र भुञ्जते / नाहं तैः सह भोक्षये वै ततो दास्यन्ति ते पृथक्
cāturvarṇyaṃ hi devānāṃ te cāpyekatra bhuñjate / nāhaṃ taiḥ saha bhokṣaye vai tato dāsyanti te pṛthak
Even among the gods there is the fourfold order, and they partake together. I shall not eat with them; therefore they will offer my portion separately.
