Dear, Currently I believe that all espiritual knowledge that we need is inside of us. Please verify if is that what you is looking for.
In other words...
Being separated, disunited, divided, seeking or fulfilling our feelings, problem solving, explanation of questions, information for decision making, within our own understanding.
Our current understanding is often focused on individualization within our own perception, so it is based on separation, on the individual's own perception, conditioned on a voluntary acceptance that we are separated from everything around us, that we are insidious and not an expression of an individuation of a whole.
We will only be able to understand this, by feeling, and in order to do that is necessary detachment of all external material life, being in this world, acknowledging this, can be the key for self realization, and have abundance in all areas of life. Mostly understanding that god is inside of us.
