Swami Vivekananda on Tantra

“Give up this filthy Vâmâchâra that is killing your country. You have not seen the other parts of India. When I see how much the Vamachara has entered our society, I find it a most disgraceful place with all its boast of culture. These Vamachara sects are honeycombing our society in Bengal. Those who come out in the daytime and preach most loudly about Âchâra, it is they who carry on the horrible debauchery at night and are backed by the most dreadful books. They are ordered by the books to do these things. You who are of Bengal know it. The Bengali Shastras are the Vamachara Tantras. They are published by the cart-load, and you poison the minds of your children with them instead of teaching them your Shrutis. Fathers of Calcutta, do you not feel ashamed that such horrible stuff as these Vamachara Tantras, with translations too, should be put into the hands of your boys and girls, and their minds poisoned, and that they should be brought up with the idea that these are the Shastras of the Hindus? If you are ashamed, take them away from your children, and let them read the true Shastras, the Vedas, the Gita, the Upanishads.”

“…denounced only the present corrupted form of Vamachara of the Tantras. I did not denounce the Mother - worship of the Tantras, or even the real Vamachara. The purport of the Tantras is to worship women in a spirit of Divinity. During the downfall of Buddhism, the Vamachara became very much corrupted, and that corrupted form obtains to the present day. Even now the Tantra literature of India is influenced by those ideas. I denounced only these corrupt and horrible practices -- which I do even now. I never objected to the worship of women who are the living embodiment of Divine Mother, whose external manifestations, appealing to the senses have maddened men, but whose internal manifestations, such as knowledge, devotion, discrimination and dispassion make man omniscient, of unfailing purpose, and a knower of Brahman. "[(Sanskrit)]-- she, when pleased, becomes propitious and the cause of the freedom of man" (Chandi, I. 57). Without propitiating the Mother by worship and obeisance, not even Brahma and Vishnu have the power to elude Her grasp and attain to freedom. Therefore for the worship of these family goddesses, in order to manifest the Brahman within them, I shall establish the women's Math.”
