Never thought of dhristi in this way. But yes, like th black hole absorbs anything near it, even light and energy, same way we can put black dot on baby cheeks. Black color does absorb more heat from sunrays than a white garmet. Interesting! I do believe that everything in this world, is energy or exchange of energy. When we talk, sound waves or energy travel and the listener receives it my movement of ear drums. Scientists have found cells in eye that receives sun light or rnergy and makes us feel good. Same way, some people have positive auora and some have negative. Every culture has something equivalent to dhristi, so let’s not worry what frech will say. Any old culture has it. May be before they started the designing of Rafael, they consulted their dead granma’s aunt, who is still living and expert on ‘how to stay thin’ as well as on how to remove evil eye from upcoming defense projects. Who knows, she might be consultant with french defense.
