Why should we be religious when the beginning and end are unknown, and there is no trace of God or soul?

According to Osho, you need not adopt 'religion' as beliefs about God or soul; the very restlessness that made you ask is the seed of true religiousness. Being religious means discovering your living link with existence—finding your roots, feeling at home in the cosmos, not an outsider. Enlightened ones cannot give you truth, only awaken thirst; follow that longing and become what you are.
