A class on Bhagavad Gita 1.41-42 given by His Divine Grace A.C. Bhaktivedanta Swami Prabhupada on July 29, 1973 in London.
Bhagavad Gita 1.41
saṅkaro narakāyaiva
kula-ghnānāṁ kulasya ca
patanti pitaro hy eṣāṁ
lupta-piṇḍodaka-kriyāḥ
An increase of unwanted population certainly causes hellish life both for the family and for those who destroy the family tradition. The ancestors of such corrupt families fall down, because the performances for offering them food and water are entirely stopped.
Bhagavad Gita 1.42
doṣair etaiḥ kula-ghnānāṁ
varṇa-saṅkara-kārakaiḥ
utsādyante jāti-dharmāḥ
kula-dharmāś ca śāśvatāḥ
By the evil deeds of those who destroy the family tradition and thus give rise to unwanted children, all kinds of community projects and family welfare activities are devastated.
