The great masters of enlightenment have different ways do describe self-realization. It depends on the philosopher. It is said that the ultimate meditation is to just sit quielty without calling sitting anything. Just sit. Regardless of whether or not you are in control over the mind if you are sitting and you are still, you are Buddah.
Other schools of thought are vastly different. It's all just philosophy, pyschology, and maybe the spark of Divine Consciousness, no one really knows the Truth about the nature of reality. Perhaps we are all one, or maybe we are all disconnected. Which philosophy leads to compassion and a happier life is up to you.
Many meditation practitioners experience something quite unique when they elevate the energy levels in their own minds to a very high degree.
The experience I speak of happens to some after they complete a very focused and powerful yoga class and then engage in a deep meditation. They begin to have a strong tingling sensation all over their body. Some of them believe that they've opened up their energy channels to such a degree that a full connection to all of the extremities of the body takes place at that point.
A practitioner might feel euphoria when he or she experiences this. They may see it as a deep connection to the divine or as something very positive taking place in their own mind. Many physical sensations might occur when it happens.
Some say that this is the zenith point of a meditation in which a lot of energy is moving around as opposed to a still meditation focused on the containment of energy. But it’s up to the individual whether to seek the “zenith” experience or to let it pass.
I personally choose to let it pass for a couple of reasons. One of them is because I seek to conduct my everyday life in a certain way that entails focused presence in the moment. I don’t want to be dependent on experiences, even particularly pleasant ones, that will distract me from the level of attention to the present moment that is crucial to my own daily practice.
