whatever one is / does must have the support of the experience of the paramount spiritual truth.

in such a light one sees all harmony in diverse ways of thinking talking and living , without running counter or in conflict with anything or any one

In the light of such perspective ,as a result of that experience, 

ultimate level of once existence 

will lead to complete harmony, in unity , 

simultaneous with existence of unique diversity of 

each and every person living his unique brand of religion / philosophy /spirituality , 

happily , complementing with every brand, and really living the single, one, universality

i expect this will surely happen , bringing all humanity under its shade, 

irrespective of unavoidable / infinite variety of participants / with different backgrounds, 

and multiplicity of view points
