There are circadian rhythms beyond which time does not exist. Our egos made up time to manage life. The concept of time likely developed with the tech of language.

When I do healing work time does not exist. The past does not exist in a place called the past but as memories that we have in the relative present. Likewise the present is only the relative present, and only really exists in meditation. The future exists as expectations, assumptions, hopes, dreams, and visions, etc. of course, we need the illusion of time to operate in the ego world of 3D.

In the world of being there is no doing.
