Good tidings, All
I feel that it is of utmost importance to develop the capacity to become impartial and empty of any expectation, when sitting in deep meditation. Just be... and in so doing, watch the watcher, watching itself, watch itself existing (ad infinitum). Calmly observing the nature of ideas arise, releasing them into the formless void, from whence they came and one finds that we maintain focus, keeping a steady concentration fixed at the epicenter of one's own being.
This, of course, brings to mind the paradox of just what exactly, is one's epicenter? I humbly suggest that each of our truest center of being is our core awareness itself. Consciousness is the underlying essence of all existence, to one degree or another. So, whatever form of meditation we embrace, the truest principles are identical, as one needs to loses oneself, to gain oneself. Meaning, the ego must be effectively silenced, to experience the reality behind the myriad appearances of this or that, inside and outside, self and other, etc...
Yogis name the indwelling self as Atman and Buddhists declare there is no permanent self at all, merely Anatma (no self). While seemingly contradictory in their emphasis, there is an agreement in that the surface of oneself is wholly illusory and the depths of oneself (or of one's no-self), there is that special something else... which is far and away, beyond the appearances of any form, is wholly eternal, infinite and absolute in it's Omniscient being. Some name it: Brahman, YHWH, Buddha Nature, God, The Tao or Allah... while some do not name it anything at all. As they say in India, "Tat Tvam Asi". We are That and naught else but That. Such a realization is sheer Nirvana! Regardless of conceptualization, without stillness within the mind, true reality cannot be directly perceived, free of the mirage of our own self-mesmerism.
I have found that through focus upon our breathing, this state can be found as most immanent, accessible and an ever-present call to spiritual awakening. Watching the breath allows the conscious-awareness to shift it's attention and bloom resplendently. Two qualities which pull my senses deeper within are the Sound Current or AUM vibration and the effulgence of the Inner Light. These are perceived by the Third Eye (or Third Ear, if you will). Attention placed on the breath, leads to direct experience of these attributes of the Divine, heretofore hidden from our understanding (itself culled from data transmitted by the five senses, deductive intellect and intuition).
Now, in combination with entheogens, awareness of our breathing is most powerful! It leads to levels and degrees of awakening, which reveal our truest nature. I often liken meditation to attunement. We are continually tuning our conscious-awareness to the quintessence of the Sacred Realm or Unified Field of Being. We are forevermore, blossoming in our exponential expansion of conscious-awareness. In this way, we are quite symmetrical and one in our innermost epicenters. We are echoes and reflections of the same Sacred Being. May you all journey deeply into your core self and discover the state therein, the transcendental pulse of Universal Awakening. Have a lovely day or night, dearest travelers through the dreamscape of the time-space-continuum. May we each find peace and moments of ecstatic-bliss, along the way.
Namaste, Rising Spirit
