Tantra is about sex, right?

No, it is not.

What is it then?

Mmmmhhh good question.

Still asking myself this question every day.

And every time I respond to it from the moment of now, I'm surprised myself what comes out of my mouth.

Tantra is a living field, it's not a concept. That's why no matter how much you talk ABOUT it, you won't get it. You need to immerse yourself in the experience in order to get it, and be open that your getting will only be deepening and expanding from there on.

The principles of Tantra are used a lot in the West in application to sex, because the practice of Tantra makes the experience of life more meaningful, including and not limited to sex. And because it is the only spiritual path that works also directly with sexual energy, it became popular in the West for "sex".

This is how paradoxes and misinterpretations happen easily.

Similarly, for instance, I heard that some thousands of years ago a bunch of monks decided to lock a cat in a wardrobe so it would not disturb them during meditation, and one monk made a note about it in scriptures. 100's years later, monks down the line believed they had to 1. have a cat and 2. lock it in a wardrobe to have a deeper meditation experience.

The purpose of walking a tantric path, from the nondual Tantric perspective, is simply to undermine your misidentification and directly reveal your true identity as that of the highest Divinity, the Whole in every part.

It is not about making you more beautiful, or more perfect as Tantra's departing point is that you cannot be more beautiful or more perfect than you already are in this moment, for nothing exists that is not God. Yet, you might not be currently experiencing reality that way due to your misperception of yourself.

The primary purpose of Tantric practice is to distabilize deep-seated, skewed mental constructs about yourself, constructs that you also project onto others in your life, until they are seen for what they are and begin to fall apart.

When you experientially realize that the same beautiful and awesome powers that orchestrate the wondrous play of this entire creation are flowing within you, there is a profound shift. Fear and smallness fall away as you realize that you've been the only one who has ever limited your potential. And then the explosion of joy accompanies the realization that there is nothing to do, nothing to achieve, other than to fully embrace the divine powers that seek to manifest through you by expressing the entirety of your authentic being in the fullness of each moment.

So, what about sex?

I'd say sex is an important part of life and if you can get to make it a great and profound experience with the powers of Tantric practices, why would not you? Besides, liberation in sex can catapult liberation in other areas of life substantially because it's one of the most suppressed areas in the collective. Realizing that sex is sacred shifts one's whole experience of it 360°.
