तेषां निर्यासरूपेण ब्रह्महत्या प्रदृश्यते ॥ ८ ॥
vareṇa jagṛhur drumāḥ
turyam — one fourth; cheda — although being cut; viroheṇa — of growing again; vareṇa — because of the benediction; jagṛhuḥ — accepted; drumāḥ — the trees; teṣām — of them; niryāsa-rūpeṇa — by the liquid oozing from the trees; brahma-hatyā — the reaction for killing a brāhmaṇa; pradṛśyate — is visible.
In return for Indra’s benediction that their branches and twigs would grow back when trimmed, the trees accepted one fourth of the reactions for killing a brāhmaṇa. These reactions are visible in the flowing of sap from trees. [Therefore one is forbidden to drink this sap.]
