Pearls of Sri Bhagavat Gita - Chapter 1.41, 1.42

                                                           

Bg 1.41,42

adharmābhibhavāt kṛṣṇa
praduṣyanti kula-striyaḥ
strīṣu duṣṭāsu vārṣṇeya
jāyate varṇa-saṅkaraḥ

saṅkaro narakāyaiva
kula-ghnānāṁ kulasya ca
patanti pitaro hy eṣāṁ
lupta-piṇḍodaka-kriyāḥ

Translation: 

Hey Krishna, with the rising of Adharma, the family women become bad. With the women becoming bad; mixing of castes takes place. The mixing of Castes leads only to hell to those who destroy the family and the family also. The pitrus of these people fall indeed deprived of pinda and tarpana.

                                                                      Import:

Only if women take care of Kulam; Kulam will sustain; and only if women takes care of Kulam; man can achieve anything or do anything further. Vali said to Sri Rama in his death bed " Do you know why you have done this? its because Sita was not there by your side " .

The whole world revolves on the great responsibilities of women and family duties, When they give up resposibilities --> Varna Sankaram ( Mixing of castes) takes place --> Thus Kula Acharam ( traditional assigned duties ordained to each caste )will go away --> Hence people will stop doing Karmas --> Thus Pitrus ( forefathers) will fall devoid of sacrifices.

Because the vedas are injuctions of the Supreme Lord Sri Hari; If we perform it; the Supreme Lord will become pleased; else it will lead to unecessary problems in life.
