In a letter to Silavati devi, Srila Prabhupada wrote, “Now if you can induce all the women of Los Angeles to place an altar in their homes and help their husbands have peaceful, happy home life in Krishna Consciousness, that will be very great service for you. The actual system is that the husband is Spiritual Master to his wife, but if the wife can bring her husband into practicing this process, then it is all right that the husband accepts wife as Spiritual Master. Caitanya Mahaprabhu has said that anyone who knows the science of Krishna, that person should be accepted as Spiritual Master, regardless of any material so-called qualifications; such as rich or poor, man or woman, or brahmana or sudra.” (June 14, 1969)
