Depends. This is where experience plays a part, because some sensations can be due to subliminal use, some are completely unrelated and due to different reasons. A lot of different things can cause sensations. Even something as simple as taking a hot shower can help energy move more smoothly, causing sensations.
A lot of the reports people try to say its due to subliminal use are in fact due to them doing weird things on the side - but usually all these other modalities don’t have active forums or creators, aren’t as well established, lack actual knowledge etc., so it’s easier to say it’s our titles.
For example, a lot of younger men are obsessed with the idea of Kundalini, so they blast themselves with YT Kundalini audios, push lots of energy up into their heads (causing a classic Western deviation of a filled up head), use much more advanced techniques than they should, and so on.
Why?
To get women.
Which is ridiculous that young men are burning their internal energy systems and causing deviations just to maybe get more attention.
And we are the ones who have to attempt to hammer some sense into these young men’s heads because Timmy from SuperSpiritualAscensionSubZ or SuperMegaSecretForums/Discord server can’t, won’t and doesn’t really care either way.
Extremely irresponsible, sadly.
As for subliminal related phenomena, it’s often subtle and more “mind” related rather than energy related, contrary to popular belief and the obsession with the tingles. And, most importantly, if there is anything energy related (such as aura or spiritual related titles), it has been developed extremely carefully and works with the natural system - so one doesn’t end up burning their energetic system as if they just blasted themselves with a faulty technique that looks cool.
Instead, the energy development is gradual, step by step, ensuring a powerful foundation and very thorough development.
So, in conclusion - you get massive tingles and scorching fire up your spine, you feel burned out, wired, etc., → you’re adding something else that you shouldn’t and messing yourself up.
You experience gradual improvement in your energy, daily state, sensitivity, feeling better and better → subliminal related (mostly spiritual titles).
It is a completely different quality, depth and level of development.
