The gift of a single Kapila cow is capable cleansing whatever sins the giver may be guilty of even if those sins be as grave as Brahmanicide, for the gift of a single Kapila cow is considered as equal in merit to that of a hundred kine.
पापं कर्म च यत् किंचिद् ब्रह्महत्यासमं भवेत्। शोधयेत् कपिला ह्येका प्रदत्तं गोशतं यथा॥
