'A incise, curious question. And these are fine answers, which many echo each the other in great measure, given in a way that each person intuitively sees and feels and yes, knows, and are expressed in each his or her own unique way to convey of truth.
Engrams -- which is what this addresses -- are true things, and there are sounds and lights and energies, which have either to flip on or off like that of a switch, and centered in a core so deep, so powerful and alive though often not till now quite ever considered or conceived of as existing, and which have only to be exposed by those whose keys and frequencies share these same or extreme opposite signatures that before lay dormant.
And each person -- strike that -- each Soul is appraised and pre-set of engrams both during processions of and before the worlds' movements in creation and sustenance -- well above duality and that of the law of the three: creation, sustenance, and reforming.
What we are is not solely dependent upon the dictates of genes as biologists let on, though genes are the channels through which engrams very often proceed and manifest, that is, are the seat and presence where they dwell, and of how comes the on and off modes, say. The mind is the other conduit as is the Heart Consciousness.
Now, Engrams, like anything in these here worlds, have light and dark sides. That is, a flipping off of one could be beneficial; and another, flipping on, can have not beneficial outcomes or expressions at all. Two, engrams are tied to karmic patterns, and with that of genetics underpinnings, these three work in tandem with the Mind and Heart Consciousness.
The computer programming model would be the closest analogy for what engrams are and do, on a much lower term, of course, for nothing can approximate sentience. And so the metaphor given here pales in comparison, but for now, that will be the closest picture and description to draw out to make the point here.
This goes well beyond anything that can be found in the Schools of Psychology, in fact beyond any the Schools of Science, for even if they should know of it, they will not truly know what this is and from where and for what reason or even that such exist as to being true-to-life things, nor what realm in which these things engrams are designed, set, and, say, installed. They do well most often set in the mind, for that is the place at which all things in the physical' have bases and grounding, but the mind is not the point of their creation and purpose -- not their birthplace or mission -- the Mind is but the instrument in no less way than one would use a horn to emanate intelligent and communicable sound, which in itself does activate engrams. Hence, bear close attention to music always.
This is a vast subject in itself and rare it is that one will be to find much of what these things engrams are but to simply use a term or wording that human beings can look to, to grasp what lies still again beyond the physically evident, and only known is it and understood within the small circle who know well of these and the, say, strange and curious art and science of what is involved and their uses. So, for purpose of communicating just what they are, allow that they be known as engrams.
Countless engrams are yet to be "turned on" in human beings, for out of these shall follow talents that have yet to be known in the world plane; from their awakenings will come great inventions and hitherto unknown fields: but much will center on light and sound. The DNAs have yet to even barely begin expressing to their full potentials. As certain engrams are cleared, so will DNAs not now expressing begin to express.
Human beings are beings with rarified and staggering abilities and powers, is all that will be said here. So what one hears in music, what on sees as to "role models," how one is raised, his familial patterns and the like have all to do with engrams... I will leave off here.
By the way, Sunman, glad to know there is a fellow drummer out there -- 'any fellow saxophone players out there, too?
