Hi Ernst,
Creation seems to be a by-product of the dreamer, the dream and the dreamed.
Because something has been created, the cycle of sustenance and destruction begins. This, in turn, causes suffering.
So, is moksha the cessation of dreaming, thus breaking the cycle of creation and destruction? It could also translate to living in the now, which could also mean being the dreamed and not the dreamer. Then, it would be a tightrope to walk on, to not create and yet not give up one's power.
Or is moksha a detachment from what has been dreamed and hence created?
According to the saints - Moksha in ultimate meaning is liberation from the cycle of life and death where the soul returns to its true state of being as Sat-Chit-Ananada - In the consciousness of truth and ever new joy. For that need to work hard under the guidance of a liberated saint's instructions for purifying the consciousness to reach to that level and get rid of ego which is holding a person back. At the end, all life is training about conceiving and working towards Moksha! "Among thousands of men, one may endeavor for perfection; and among those who have achieved perfection, hardly one knows Me in truth." This shloka from Gita.
Your question made me think of two books that you may enjoy that relate almost entirely to your question:
I am That, Talks with Sri Nisargadatta Maharaj
and
Talks with Sri Ramana Maharshi
You can find both as pdfs if you so desire.
Moksha means freedom. It happens on many levels and it is essentially health.
Are we free from physical disease or does out body keep us bound from doing something we want to do?
Are we free from emotional disease or do our emotions pull us here and there and cause us to respond in ways we wish we had not.
Are we free from mental disease or are we acting on wrong ideas that we think are true to us and which we don't even question?
Once we have these three mokshas, which can be explained and understood. Then we can grasp what spiritual moksha really is but we will never be able to clearly explain it but we can read those good books mentioned to help inspire us.
Moksha isn't cessation of dreaming. Rather its a stage where we accept that every phenomena (dharma) in existence is impermanent (anicca/anitya) and devoid of self-existence (anatta/anatma). Suffering comes when we grasp onto these dharmas as being permanent, and thus we are unable to accept that things change.
Suffering itself is of three types - suffering of suffering (dukkha dukhhata), suffering of change (viparinama dukkhata) and suffering from mental condition (samskara dukkhata).
In moksha, mind stays calm and uniform, not overly thinking, overly feeling, overly grasping, a perfect state of equanimity (upekkha/upeksha).
