The following two (separate) quotes by Srila Prabhupada are about the potential for women in the Krsna-consciousness movement:
Prabhupada: "Yes. Jahnava devi was – Nityananda's wife. She became. If she is able to go to the highest perfection of life, why it is not possible to become guru? But, not so many. Actually one who has attained the perfection, she can become guru. But man or woman, unless one has attained the perfection.... Yei Krsna-tattva-vetta sei guru haya [Cc. Madhya 8.128]. The qualification of guru is that he must be fully cognizant of the science of Krsna. Then he or she can become guru. Yei Krsna-tattva-vetta, sei guru haya. In our material world, is it any prohibition that woman cannot become professor? If she is qualified, she can become professor. What is the wrong there? She must be qualified. That is the position. So similarly, if the woman understands Krsna consciousness perfectly, she can become guru. (Interview with Professors O'Connell)
Prabhupada: "If a woman is perfect in Krsna consciousness... Just like Jahnava-devi, Lord Nityananda's wife, she was Acarya. She was Acarya. She was controlling the whole Vaisnava community." (Interview. Toronto, 18 June 1976)
The prostitute shaved her head clean in accordance with Vaisnava principles and stayed in that room wearing only one cloth. Following in the footsteps of her spiritual master, she began chanting the Hare Krsna maha-mantra 300,000 times a day. She chanted throughout the entire day and night. She worshiped the tulasi plant, following in the footsteps of her spiritual master. Instead of eating regularly, she chewed whatever food she received as alms, and if nothing was supplied she would fast. Thus by eating frugally, and fasting she conquered her senses, and as soon as her senses were controlled, symptoms of love of Godhead appeared in her person. Thus the prostitute became a celebrated devotee. She became very advanced in spiritual life, and many stalwart Vaisnavas would come to see her. (Caitanya-caritamrta, Antya-lila 3.140-142)
