Hinduism, Initial concept of Shiva, Trinity...

[PARAMASHIVAN]

My question is: Looks like one group of people who were part/ influenced by the Semetic religion migrated to India in some historic timeline, who considered Brahma as their roots, worshiped him and then looking into the local trend of religion which was Shiva worshiping, brought in the concept of Trinity as part of unification??? When they brought in the concept of Trinity to maintain their strong hold they added Brahma in the first and then moved the local god to the lost???

As you know India had been under many invasion, sanskrit was introduced by various invasion from persia, babylonia and as far as Turkey. It is all part of evolution.

Besides, the Creator of the cosmos alias GOD is not an external entity , it is within you. All religious sects preach the Lord is an external entity, but only in what is called hinduism (name given by Persian invaders) it is taught to realise that the Creator is within you by various forms of Meditation/Yoga and self realisation.

BTW Shiva is considred to be the Adhi Yogi (The Enlightent one)
