Conditions that promote 'Lucid Dreaming'.
A large topic to be sure. Very large as I am convinced it touches to conscious evolution itself.
I first got the idea of pursuing Lucid Dreaming more systematically 25 years ago. It occurred prior (I was 27 then) but I regarded it as something that happened from time to time and seemed to always mark a change.
However, I came across an old metaphysics book, first published as a book in 1903 I believe, from being a monthly correspondence course for a few years prior.
The book went on to be a large seller, which is probably why I found it available. It mentioned or outlined ideas to 'creating new brain centers' that would be actual. Creating any new center would take concerted effort in one line of endeavor over time by intensity.
Which is to say, time taken is relative to consistent discipline in thought and action. It combined thinking logically to an end and also doing physical exercises meant to assist mental development.
Most all of this kind of material (no matter specifics) runs along a general line of focus, logic and application. This can include reciting or memorizing verse, breathing exercises, employed life-style routines that support new supportive habits.
Like reviewing backwards each night all that had transpired that day, to include conversations, going and comings of the day.
It could include visualizations, mantras etc. etc. There are 'volumes' filled with such counsel.
But what I have found to be ever consistent; can be summed up in this statement:
'When conditions are right it works!'
So one 'nurtures' them. Such as clearing the psychic clouds of clatter, breathing clean air, sipping sacred water. (anything blessed) etc.
I do not think any one formula is certain to 'Lucid Dreaming'. I am sure it varies as people and their temperament varies.
My first thoughts...
