Sadhguru
How do I stop lying about things I don't actually know?
Speak only of what you experience
Talking about what is not yet in your experience amounts to lying. Do not talk about the soul, heaven or God when they are not a reality for you. If you refrain, a certain longing will appear within you which will lead you there.
If you talk about something which is not yet in your experience, to put it very bluntly, it amounts to lying. So this is the first thing you must do: you must stop lying.
