Oneness is a spiritual phenomenon suggesting that All is One, that all living creatures and materia are tightly connected and we can percept and enjoy that.
Some people get fantastically beautiful experiences of Oneness, I posted already the story by Daniil Andreev, let me quote it:
“Everything on Earth and everything that must exist in the heavens poured exultantly and noiselessly through me in a single stream. In bliss barely supportable by the human heart, I felt as if slowly revolving, graceful spheres glided through me in a universal dance, and everything I could think of or imagine merged in a jubilant oneness.
The ancient forests and clear rivers, the people sleeping by the fire, the peoples of countries near and far, cities waking up and busy streets, cathedrals with sacred icons, seas tossing tirelessly, and steppes with blowing grass— everything indeed was within me that night, and I was within everything. I lay with eyes closed, and beautiful white stars, large and blossoming, not at all like those we are used to seeing, also floated along the world-turned-river like white water lilies.
Although the sun was not visible, it was as if it, too, were flowing somewhere just outside the range of my vision. Everything was suffused not by its glow but by a different light, one I had never seen before. Everything flowed through me and at the same time rocked me, like a child in a cradle, with all-soothing love.”
I am in awe of that overwhelming feeling! I could never experience that, at the most just the feeling of dissolving in the sorrounding.. Another stunning experience of Oneness I found in the book I reviewed recently here.
My personal experience of Oneness is much more modest, but luckily ongoing. Before I started my sahaja meditation practice at 20 I was a highly individualistic person, afraid of any groups and feeling very isolated because of my “different” interests in life. I had one or two friends and that was enough for my social sustenance.
After taking to meditation practice I noticed that my interest and ultimately love for people would slowly but steadily rise. I started enjoying people more and more. A lot in human behaviour was still a great puzzle to me: for instance I could not understand such things as jealousy, grid, being offended, etc. Even now I don’t understand all that but it does not disturb me any more.
Over the years when my spiritual experiences were taking me deeper inside my being I realised that I would not only love people, not only would feel their worries and joys on my body but people, ALL people, were becoming my close friends, or even relatives.
The most amazing thing about this feeling of Oneness is that it is not mental: I do not feel being one with everyone because “we are all children of God” or any such concepts. This is a feeling that the person next to me is just the extended part of my body, just the next family member, another friend!
People also feel that and many say when they meet me for the frist time they feel so comfortable and familiar, like meeting an old friend.
Again I would love to underline that this experience was gained over the years and not by any mental exercise, belief or teaching. This can happen if one allows the inner powers to wake up and enlighten the shoul, the mind and the heart.
