Sadhguru

Is it a lie to speak about the soul or God if I have not experienced them?

Belief spoken as fact is a lie

You know you have a body, and to some extent a mind, but the rest is belief. Talking about what is not yet in your experience is, put bluntly, lying.

If you talk about something that is not yet in your experience, to put it bluntly, you are just a liar. That is what it means.
