Question: What is Reshimo (reminiscence)?
Answer: A Reshimo is what has already happened, a previous spiritual state, since nothing disappears in spirituality. The previous states that emerge in every detail but don’t manifest in life due to the lack of the screen which serves as the means of their realization are called “Reshimot.”
Suppose yesterday I was in some state, and today I am reliving it. In spirituality, this state emerges in me in its every minute detail, as if I am living it right now. It is totally, 100% clear to me what is occurring, and nothing is lost; I simply cannot realize it due to lack of the screen. This is called “Reshimo.”
It is not a recollection of the past as in the corporeal world when I remember something “vaguely.” A Reshimo is when I don’t doubt anything; everything is revealed as in the present except for its realization.
