There is no scientific proof for the Divine that can be peer reviewed and accepted by hard materialist science.
Meditation, awakening the deeper emotions of devotion, divine love, compassion, benevolence, and fearlessness all this helps the consciousness grow out of its skin wrapped condition in to a state of universal connection and transcendental identity.
The I am the body alone idea causes us most of our sufferings. All bodies, all beings, the earth is a ripple on the surface of our eternal supreme being. We literally are the supreme divine being in which all this cosmos takes its stand.
We are Buddhas but asleep, therefore waking up to who we trully are fufills the purpose of birth and heals the divisions and discords in our world if it happens on a collective level.
"That which permeates all, which nothing transcends and which, like the universal space around us, fills everything from within and without, that Supreme non-dual Brahman - that thou art." Adi Shankara
