According to Osho, yes, doubt alone blocks realization that we are already home. Conditioned to self-condemn and to project God far away, we distrust our own being. The kingdom is within; nothing is missing. Drop the perfectionist chase, relax into your present awareness, and trust your intrinsic worth. Then gratitude arises naturally, revealing your life as God's abode, here and now.
You are already home inside; stop believing you are broken or that God is far away, just relax and trust your own heart.
