What is often implied with telepathy, is a form of a communication that would happen directly in the headspace. That is basically to say that to "evolve" is to not need mouths, a very complex and feminine organ, but rather to simply leave that behind, for something abstract, a mind floating without body.
The idea of telepathy is as such very powerful, what dreamers seek not to fly ?
It also follow similar order as other ideas, like breatharianism (to feed without mouth) or most model of transportation invented by man (instead of using the hips, belly, region to move, and to have our hands free and relaxed, we need to grasp and direct things with the shoulder region). But it also find a more perfect incarnation in letters or digital communications. Both teleporting thoughts in the distance. And again, whereas with a pen you would write with your all forearms, or as the Chinese calligrapher 'paint' with their all body, you type on a machine with very segmented sensations, very limited to the tip. It is very articulated. In a sense, it follows also a similar pattern as music, which would have at first be sung, then blown, and eventually only played, with no more mouths, no more breath and only fingers. The very mental, numeral and precise fingers.
What this imparts, is that whereas with your mouth, you need be aware of breath, and of the need of a pause, that we have made sound instrumentalized has made it perpetual. So it is basically the same idea as eternal growth that is so dear to our beloved neo-liberal society. It can seemingly go on. You can read a book of a thousand pages, and whereas the narrator, or yourself if you were to speak up of what your eyes befall onto, would need to rest, that they would feel the physical limitations, the soar mouth, the mind can go fast, seemingly unbounded. As such, the body is entirely excluded from this extremely visual, out of body experience that is the digital rein. If you are to personify a little our present model of communication, we are literally beings of light reduced to a written from that could outlast us. I could still exist by those words here if I wear to get a virus in the near future. In other words: Eternal Being of Light Immortal in the Cloud (™)
So, if we study our desires, we actually get a more accurate pictures of this affair, that transcends cultures but it surely most representative of our death fearful one.
However, they might already exist of forms of telepathy. They might be rooted, not in something extremely abstract but something extremely physical. The language of body is universal. And it tells a lot ! But maybe, because we are a little to overwhelmed and focus on what goes on inside our bubble refractory mirrors, we don't notice every subtle details that we should, and that always speak more to our true intent, rather than the lies we can tell ourselves. To eventually heightened those sensations (thought it might not really be needed, everyone has hobbies!), the way would most likely be to simply look down where instincts lies, out of control, to this vague regions, this belly from where we were born and seem to be so eager to leave.
Any way, the best way to feel that thing, that link, might just be to keep close to the ones you care about. In that good, well sung, old silence.
