Integral Unity of Sanatana Dharma (मूलसिद्धान्तसमैक्यता)

Unity of Mula Siddhantas of Sanatana Dharma (Samskrit : मूलसिद्धान्तसमैक्यता) of dharma stems from only vedas and rest entire only vedas.  Over thousands of years, over millennia, countless number or rshis have rested upon just this one point - Unity of Goal amidst Diversity of Paths.

Rshis may be many, but vision is just One. RigVeda (1.164.46) says

एकम् सत् विप्रह् बहुध वदन्ति || ekam sat viprah bahudha vadanti || (Rig. Veda. 1.164.46)

Ekam sat, that which IS, that which Will Be, that which never gets corrupted that is One, but the rshis, speak of Him, the wise people speak of Him, in many ways.  

If this was not true, truths would have been varied from Rigveda to Yajurveda and from there to Samaveda and from there to mahabharata to Puranas.   T know, what is holding us up altogether is its mula siddhanta, this ikyata, and unfortunately during later days, in the what western people call the medival year, vedanta came to be interpreted in diverse ways giving room for fictions, misunderstanding, and some amount of negativism was introduced into that mula siddhanta, through non Vedic religions.
