cubibobi asked: “Is it correct to say that the sounds coming out is vaci sankhara, and the ideas emitted from the thoughts mano sankhara?”
No. Mano sankhara arise automatically due to our gati.
Vaci sankhara are what we CONSCIOUSLY think and speak.
See, “Sankhāra – What It Really Means” and “Correct Meaning of Vacī Sankhāra.”
Please feel free to ask questions, if not clear.
