Here’s the funny thing: Western meditators I’ve met often brag how they’ve “conquered” or “mastered” their libido by reducing it through meditation. However, tantric yogis in India and Taoist cultivators I’ve met often indirectly brag about their virility, which is often connected to their ability to first channel it through deep silence and to refine it through breathing/visualisation or other techniques.
Also note how monastic orders like the Buddhists intentionally starve themselves to a certain extent by going vegetarian, eating only one bowl/meal a day and avoiding all type of foods that increase your libido. Whereas tantric and Taoist yogis often intentionally eat as much meat and libido improving foods as they can get their hands on. Very different priorities, because they understand our bodily needs intuitively and are generally not under monastic pressure to appear holy or not cause trouble.
In practical terms, the sexual energy which manifests as libido is a natural charge that builds up, but there is also a limit to it, set by your inherent capacity(some people naturally have a high libido, after all). This capacity can be increased through deepening your inner silence through whatever means you can find. The most common theory I’ve encountered is that energy follows intent, and many intellectual thoughts disperse energy in all kinds of directions(hence why artists and scientists seem to benefit from celibacy from time to time). Remove the various thoughts, and you are back to the natural state where your sexual energy optimally recharges after depletion through sex or masturbation.
The most interesting thing is what happens when you go into deep silence for prolonged periods of times. The famous “100 days of setting the foundation” as a formal stage in Taoist cultivation is just that. The real challenge is not to have any sexual thoughts because they instantly convert the energy into semen for procreation. You have many religious orders that enforce celibacy, but don’t tell their members why. So while they may refrain from having sex, they still think about it, and keep converting their energy down. And once it turns into semen, it is no longer usable for energy cultivation.
So real meditation would have to be supremely disciplined, especially when you come from a background like mine where you have been hammering your mind with porn for several decades in a row. It’s like when you say “don’t think of the pink elephant!” and can’t avoid visualizing it. Hence why Khan Black would be really useful for that end, too. If you remove the original addiction and habit, it becomes easier to regain your youthful energy and ambition.
The idea that meditation reduces your libido(beyond the initial stage) seems rather strange, considering that for example the Longmenpai Order of Wang Liping is literally focused, in its beginner program, to “restore an adult man to the energy configuration and libido he had when he was 16”(their words, roughly translated). You are supposed to get spontaneous erections at some point. Of course, these sadists want you to have boners and absolutely avoid having horny thoughts. But yeah, there’s many layers of complexity to these things.
So there is deep energetic consequence in meditation/ what you call inner silence, on top of regular meditation benefits.
