Interesting...would you know which texts Sri Aurobindo was referring to ? > Beyond Agni is Vayu of which science knows nothing. > It is the support of all contact and exchange, the > cause of gravitation and of the fields (magnetic > and electric). Modern physics recognizes four forces of nature which need to be unified into a common theory: Electromagnetic Weak nuclear Strong nuclear Gravity. I am guessing Vayu would correspond to all these 4 things. > And beyond Vayu is the ether, Akasha. What would be the constituent elements of (say) Chidakasha ?
