Om Swami
What happens if I keep lying to myself until I believe it?
Believing your own lie
You can lie to the whole world, but not to yourself. If you learn to lie to yourself and start believing it, no one can save you, and you may refuse even the truth when it knocks at your door.
Many times you take your own untruth for such solid truth that even if truth itself comes and knocks at your door, you do not open it.
