Common root of most religions

In response to Religion and Control, someone posted: Well said, Samiya. But are not the writers of scriptures also 'leaders' and those who chose to follow the scriptures being followers?
Answer: Indeed, yet like in all things in our world, each has the potential for the good, for the bad, and for somewhere in between the spectrum.
I believe that the prophets were divinely inspired, bringing the same message, the scriptures were originally pure guidance from God, but later on, individuals in these groups decided that they were 'holier than thou', and sought control, establishing themselves as holy leaders [priest], morphing the message to suit their needs, and gullible people just went along and became their followers.
Nearly all major religions' original texts contain glimpses of the divine message of a single deity, piety, charity and love for all. Even hinduism's most sacred text, the Vedas, speaks of one God, of the grave sin of joining others in the worship of the One God, of sacrifice, of eating meat, etc. That the hindu religion as practiced today is of a pantheon of gods, worshipped and prayed to, appears totally contradictory to the message of the Vedas. I haven't read the holy book of the Zoroastrians, but when I visited the ruins of Persepolis, had I not known that this palace belonged to a Zoroastrian king, I would have thought that the proclamations engraved on the walls and pillars had an Islamic background, so similar it was to our beliefs and practices. Abraham and Moses preached of One God, the Torah of the Jews, contains the same message. The ten commandments resonate that common message. The Bible contains verses about the one and only God.
Have collected some web links below.
