Energy is the ultimate Truth. It is not inanimate. It is so lively with intelligence. So energy is the most important characteristic in living organism as well as nonliving things. The whole cosmic dance is only due to the energy and due to its conversion from one form into the other. If such conversion is to the maximum utilisation to the human then we term that as most economical. If such conversion is bringing peace over all then it is termed as political. (don't consider present politics. It is not at all politics. It is totally a loot) If such a conversion is highly distributive then it is social If such a conversion is well understood then it is science. If such a conversion is fully realized then it is wisdom If such a conversion is witnessed then it is enlightenment.
