Separation is uniquely “I” (ego) based. That is, whatever reasoning or beliefs you adhere to, whether religion, politics, nationality, gender, ethnicity, social status, education, etc., you are the sole source of separation and any discord you sense is with that which lies outside your point of view. Furthermore, those who subscribe to your separation (agree with you) do not make you “one” with them. It just feeds your ego with the security of numbers, e.g., “look at all those who feel and believe as I do. I (we) must be right.”
Your “truth,” as it is bandied about in spiritual speak, is not truth if in any way it separates you from another, regardless of any moral code you subscribe to. Oneness is love, and love is without reason of any kind. Sinner or saint is not distinguishable. Love is our core and thus surrounds us all.
