Although the exact time/origin of this tantra has not yet been established firmly, the text is presently being quoted more and more (thanks to the translation by Christopher S. George) and is being recognized as one of the more important scriptures of Vajrayana.

There is little to comment about the following selection of quotes from the text, the words clearly speak for themselves. We are clearly dealing here with ritual sexuality, and with worship of the yoni:

One who, possessing desire, represses desire, is living a lie.

Take refuge in the yoni of an esteemed woman.

She should have him suck her Lotus and show his pleasure. Inhaling the fragrance, he should enter with his tongue, searching for the Red and White secretions. Then she should say to him: Eat my essence! Drink the Waters of Release! O Son, be a slave as well as a father and a lover.

This is the best diet, eaten by all Buddhas.

Women are heaven; women are dharma (truth);
and women are the highest sacrament.

Women are Buddha; women are the sangha (community);
and women are the Perfection of Wisdom.

The man sees the woman as a goddess. The woman sees the man as a god. By joining the diamond scepter and lotus, they should make sacrifices to each other. There is no worship apart from this.

Kissing and embracing, he should always worship Vajrayogini. Physically if he can, or mentally and verbally if he cannot. The aspirant who satisfies me wins the supreme attainment. I am identical to the bodies of all women and there is no way that I can be worshipped except by the worship of women. Visualizing that she is fully my embodiment, he should make love to his woman. Because of uniting the vajra (phallus) and padma (vulva), I will grant enlightenment.

Therefore, one who desires Buddhahood should practice what is to be practiced. To renounce the sense objects, is to torture oneself by asceticism - don't do it!
When you see form, look!
Similarly, listen to sounds,
Inhale scents,
Taste delicious flavors,
Feel textures.
Use the objects of the five senses -
You will quickly attain supreme Buddhahood.

Constantly take refuge at my feet, my dear ...
Be gracious, beloved, and give me pleasure with your diamond scepter.
Look at my three-petaled lotus, its center adorned with a stamen.
It is a Buddha paradise, adorned with a red Buddha,
A cosmic mother who bestows bliss and tranquility on the passionate.
Abandon all conceptual thought and unite with my reclining form;
Place my feet upon your shoulders and look me up and down.
Make the fully awakened scepter enter the opening in the center of the lotus. Move a hundred, thousand, hundred thousand times in my three-petaled lotus of swollen flesh.

I must practice devotion to women
until I realize the essence of enlightenment
