The only way out is In
You are programmed to desire pleasure and to avoid pain.
Unfortunately, they go together. Everyone has this experience.
The only way out is In. That is why you are a seeker. Really, everyone wants to feel good. Your journey of self-discovery is a search for truth, bliss, love and freedom from suffering.
All unenlightened people suffer from separation. All enlightened people enjoy Wholeness.
The journey is from separation to Wholeness. Your separation has a beginning and an end. In between there are perhaps a hundred lives. When the time of your reunion comes closer, you often feel the Dark Night of the Soul.
Do not despair. It is always darkest before dawn.
