There is a very small but non-zero proportion of humanity that will benefit greatly from this (sort of thing.) Roughly those who are on what is called the "mind-only" path. (Vulcans, from Star Trek.) For them this is a profound and deep proof.

Once as a small child I experienced spontaneously unconditional love for approximately twenty seconds. Subjectively I felt a deep and abiding love for all things everywhere. The Universe itself was a small thing embedded in an unbounded ocean of love.

In a certain sense the experience never left me as the memory of it is a kind of background and foundation to the rest of my life.

I won't wax too mystical here on HN, but in time I found that love is a physical reality that undergirds the world of form, that the real world is an expression in different modes and frequencies of love. E.g. gravity is love. All matter/energy yearns to return to itself in the unity that existed before Time.

BTW, there is a simple algorithm to enter and experience "higher" subjective realities. It's called "Core Transformation Process" and, as I said, it's a simple, easy, fast, effective algorithm. https://www.coretransformation.org/
