According to Osho, the 'door' in spiritual teachings is the inner opening of awareness through which nature’s unconscious ecstasy matures into conscious celebration. Man is that threshold: a seed of potential moving from homelessness to a higher home. Religion and meditation complete the journey, turning mere possibility into realized being—passing through the door from meaninglessness to fulfilled, harmonious life.
The door means waking up inside so you can go from feeling lost to feeling at home in yourself.
