SB 6.14.40
dhig aprajam striyam papam
patyus cagrha-sammatam
suprajabhih sapatnibhir
dasim iva tiraskrtam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
A wife who has no sons is neglected at home by her husband and dishonored by her co-wives exactly like a maidservant. Certainly such a woman is condemned in every respect because of her sinful life.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
As stated by Canakya Pandita:
mata yasya grhe nasti
bharya capriya-vadini
aranyam tena gantavyam
yatharanyam tatha grham
“A person who has no mother at home and whose wife does not speak sweetly should go to the forest. For such a person, living at home and living in the forest are equal.” Similarly, for a woman who has no son, who is not cared for by her husband and whose co-wives neglect her, treating her like a maidservant, to go to the forest is better than to remain at home.
