Rig Veda...

"Meet together, talk together, let your minds apprehend alike: in like manner as the ancient gods concurring accepted their portion of the sacrifice.

Common be the prayer of these (assembled), common be the acquirement, common the purpose, associated be the desire.

I repeat for you a common prayer, I offer for you a common oblation.

Common be your intention; common be your heart; common be your thoughts, so that there may be thorough union among you."
