स्वमांसं परमांसेन यो वर्धयितुमिच्छति ।
अनभ्यर्च्य पितॄन्देवांस्ततोऽन्यो नास्त्यपुण्यकृत् ॥
svamāṁsaṁ paramāṁsena yo vardhayitum icchati |
anabhyarcya pitṝn devāṁs tato’nyo nāsty apuṇyakṛt ||
(Manu Smṛti: 5.52)
“There is no greater sinner than one who seeks to increase his own flesh with the flesh of others and does not worship the forefathers and devas.”
