One can also think of the psyche as a process of mediation or digestion between soul and matter, or as the "glasses of the soul" with which it sees the world: wherever the psyche has "a hanger", spiritual development goes wrong, because the wisdom of the soul cannot have a direct effect on our lives, but is distorted.
That is why it is so helpful for spiritual development to clarify the psyche so that our soul can express itself as directly and unadulterated as possible in this life.
Especially with strong spiritual experiences, seminars or channeled messages, the problem often arises to integrate these experiences well: they often become "hard-to-digest chunks", which require a lot of gastric juice, i.e. a lot of work of the psyche, in order to become digestible and often tempt to "lift" from the normal reality of life, because the spiritual world seems much more attractive than the often relentlessly real life.
This is the small-step work of psychotherapy: we "chew" the big chunks over the physical-psychic and make them digestible, i.e. digestable and integrable for the current state of development of the psyche, so that the deep spiritual experiences really translate into the reality of life and lead to a fulfilling and "effective" life in this world - the purpose of our being here.
