Accepting gifts (especially land) at ritually sensitive times like an eclipse or during sūtaka can generate fault; a specific, limited penance—fasting for three nights—purifies the receiver and removes the resulting demerit.
In the Anuśāsana Parva’s dharma-instruction, Bhīṣma is teaching norms of conduct and expiation. Here he gives a practical rule: if one has accepted a land-gift under eclipse-time or impurity conditions, one should perform a three-night fast as atonement.
