It was stated in the previous issue of Sudarshanam that women should not chant Vishnu Sahasranama, are there any scriptural proof or any reference by our ancient preceptors?

Proof lies in the practise of our virtuous elders. It has been approximately 5000 years since the birth of Vishnu Sahasranama, our elders have paved a practise from then and till now, so we follow their way.
