Non-duality is a yogic philosophy, which shares striking similarties with the Essenz. The similarities reinforce the theory that the Essenz was and is the original way of being, which people around the world personalised according to their culture.
Non-duality basically states that we do not have a separate self or individual identity to our original state of being which is I AM, the original consciousness that lives in the here and now as a unified whole with all life.
What is known as the individual is an entity that is created through the medium of our ego. This entity removes us from the here and now and provides us with a past and a future. It misleads us by identifying with our thoughts and emotions and believing them to be real. Ego is terrified of losing control over the self-created illusion and for as long as we believe in our ego, we endure suffering, the rollercoaster of our emotions and thoughts, and a path that takes us away from our originality.
There is a series of videos by Pernille Damore, a Danish naturopathic doctor based in the UK, which are very good in explaining the concept of the Essenz - even if she calls it self-enquiry, direct experiencing and non-duality. What she is essentially talking about is the Essenz.
The truth of how much we are held ransom by our ego is something that non-duality and the Essenz excel in. If you wish to experience life as it genuinely is, and move beyond the illusion and delusion of ego, to return to the unified calm, peace and oneness of life and our inherent nature and being, then embrace your original Essence.
