Emptiness.

i think i experienced Samvega, appreciated by Buddhist Monk Bhikku Samahita, Samahita Thera from Sri Lanka.

i think i experienced impermanence & suffering to a certain degree in my life as well.

i think this leads to understanding Emptiness, to understanding ideas of Mind,
of Consciousness & of No-Self.

i think - but probably it's imperfect still to think that way - i think we are Consciousness ... the feelings, mind states & reality we cognize are nonpermanent, are changing, are causes of suffering.

i think non-permanent nature of Ego, as well as non-permanent nature of Self is key to understanding idea of No-Self, is key to Liberation.

i think concept of Ego emerges from early childhood & from previous lives - we perceive something 'external', then this duality makes us separate between 'perceiver', 'perceived object' & 'act of observation'. i read it's false concept, in truth there's only consciousness as a whole, instead - where 'perceiver', 'perceived object' & 'act of observation' are together, a unity, a whole.

it's mostly conceptual thinking for now, my experience is limited still.

i've learned from the Internet Video Lessons of Bhikku Samahita, Samahita Thera a little about Emptiness & related Ideas.

i wish to learn similar lessons from Lama Ole Nydahl or from HH Buddha Karmapa 17th Trinley Thaye Dorje as well, if possible, as soon as possible - but not at all cost.
