The effects of all our actions occur through a probability space. Some things have much higher probability of inducing certain reactions, some of the others have a more unpredictable nature, some have low probabilities depending on what the chosen goal is. You can only perform actions in probability spaces, however the ultimate effects of your actions are driven by forces outside your control.
For example: A particular song may induce certain types of feelings in me. The overall pattern is highly probable However the exact feeling can never be recreated. There is a whole gradient of probabilities in awareness. Like if you are sick, in a very bad mood, tired, even the best songs would not be enjoyable. Whether or not some action of your will satisfy you is also a probability.
Maybe, in the previous weekend, when you had a night out and drank 4 beers, it was memorable. So you may do that again to repeat the ‘memorable’ aspect, but that again is a probability. It may or may not be memorable. Also the exact flavor can never be recreated.
These probability spaces at every moment are vibrating, pulsing, dancing etc. which is the ecstasy of life. The more deeply you look, the more vibration is found. For example, your table looks stable. Look at it with microscopes, going progressively deeper, you’ll reach a point where electrons are moving in warp speed and your entire table is made up of those warping vibrations. The same applies to your DIRECT experience of anything. The amount of vibrations you perceive depends on the extent to which you have developed your awareness.
So every moment is completely unique. When this fully sinks in, it creates a mixed feeling of euphoria and discomfort. The discomfort is because of the groundlessness. The euphoria is because your true identity is this infinite space of manifestation.
