Since hinduism believes in transmigration of souls, if someone kills a chicken or sheep or mosquito, is it possible one has killed ram or raavan or krishna?
Transformation of soul is nothing but transforming of energy into other form, in Hinduism,is the oldest form of religion as compared to other religions which are just 2 to 3 thousands years old, which previously dominated by Rishis as oldest form of scientists in every area, they described the complex things or topics in easy and understandable meanings, they know the truth of life hence they created meanings to describe it to common people, now imagine ten thousand years back in time, people of that period, who were believed in supernatural power, would not like to listen the truth, hence Rishis described in religious manner,all the things which was described in religious books were not in the same meaning. but they have meanings in other form, it is up to you which meaning you like as per your knowledge of nature.
In Hinduism, The great Rishis know that all the life on earth is created by Sun energy, hence they started the day with Surya Namaskar ( Giving thanks to Sun i,e. the father of all energy) and they also worship Shiva as the the true energy, because all the planets, sun, stars and matters you see in the universe are form of energy, it is the ultimate source of life and universe, so if you want to understand it you have to leave the religion aside and because just saying all is created by god/allah or some other supper power mean s you do not want to understand the Nature.
