What do you believe in?

There’s this thing troubling me all my life. Going to temples, finding peace, divinity, contemplating. Supposedly. And one fine day, what the hell.You don’t feel anything. The idol in the shrine no longer appeals to you. You begin to wonder how a stone sculpture can move millions of people, spiritually, emotionally. How one can explain piercing your tongue, or shaving your hair, or slaying a goat in the name of sacrifice or rituals? What explains this mindless acts beyond logic performed in the name of “God”?
