A Brahmana who is distressed through a want of means of subsistence and pines (with hunger), (but) unwilling to adopt a Vaisya’s mode of life and resolved to follow his own (prescribed) path, may act in the following manner.
A Brahmana who has fallen into distress may accept (gifts) from anybody; for according to the law it is not possible (to assert) that anything pure can be sullied.
नाध्यापनाद् याजनाद् वा गर्हिताद् वा प्रतिग्रहात् । दोषो भवति विप्राणां ज्वलनाम्बुसमा हि ते ॥ १०३ ॥
By teaching, by sacrificing for, and by accepting gifts from despicable (men) Brahmanas (in distress) commit not sin; for they (are as pure) as fire and water.
Agigarta, who suffered hunger, approached in order to slay (his own) son, and was not tainted by sin, since he (only) sought a remedy against famishing.
