There are forms of advanced eastern meditations where the practitioner is instructed to focus on the sensations of different points on the body, like the hair of the head, and then hair on the body, and then eventually the organs, feeling the liver, the kidneys, etc
It might be prove extremely difficult in the beginning, but after diligent practice you can get a real sensation of feeling where it goes.
A mentor of mine once told me about having watched a shamanic master downed a handful of supplements, herbs, other drugs, etc to “feel where and what region of the brain they activate.
He was able to trace what lit up and where it would travel to next.
Similar thing.
One of the only reliable ways you can substantially increase your IQ is through developing your sense-abilities, and you can literally practice this anywhere at any time just by looking at an object and vividly describing it in as much detail as you possibly can, and in every one of the five senses.
After a while of diligently practicing THAT, the result is just straight up bizarre. Your ability to grasp the world increases ten fold. You’ll listen to someone recounting an experience they had and you’ll see it in 4K ULTRA HD (and sometimes see the exact scene they’re describing)… you’ll see movies when you read books, etc.
You can develop synesthesia (cross senses; hearing colours, seeing smells, etc) by doing this.
I’m fluent in more than one language and conversant in a few.
Have you ever heard the advice of brushing your teeth with your non-dominant hand?
Well, recently I’ve taken to reading books in other languages and noticed the synesthesic experience is completely different, with a whole new set of textures and colours not available (at least, to me) in English.
This extends to speaking, but to a lesser degree. With the languages I’m not as skilled at, I have to really lock in and give my full concentration to understand what is being said.
I want to encourage you to think about how much further you can develop your brain by practicing it’s perceiving functions in new and challenging ways. Practicing mindfulness by noticing all the sensations. Right now, without moving your feet, become conscious of where your toes are sitting and how they feel in space. Notice your breath, watch your chest as it rises and falls. Close your eyes, count how many different sounds you can become aware of that you were previously tuning out. Learn a new language, go travel to a country where English is not the primary language and force your brain to adapt.
By doing this, you will grow and train your brain tremendously, and that will translate into other arenas in ways you could not possibly imagine.
Raise your IQ, enhance your ability to sense and perceive, and expand your capacity to grasp phenomena of all kinds.
Namaste.
