I am impressed with your sharing on the interpretation of the meaning of the word Sanatan. The word as it is derived from Sanskrit. I would like to learn why polytheistic practices are associated with 'Sanatan' dharma. If you read the holy Qur'an, you may learn that communications for monotheistic command has been there in all the time through the messengers. I call for adherence to the monotheistic commands.
Would not it be nice to collect the monotheistic commons across the sacred texts and unite people in adherence to the commons.
