I don't know that I can say I've had many religious experiences... I mean I've been to church. But I don't know that I can say I've ever felt a part of a sacred or spiritually significant event that demonstrates proof of a deity or justification of faith. Some would argue that proof is in everything from the minutia of our daily lives to the beauty of nature to the miracles of love and birth. These are wonderful things to be sure, and my heart does swell in those moments when I stop to smell the proverbial roses.
Still, I'd like to think that we all have our own two-headed cow, whether we consider ourselves to be spiritual beings or not. Something we journey for, to fill our hearts with love and wonder, to fill us up so that we can keep going. This is slightly embarrassing, but my two-headed cow might be my cats. My daily pilgrimage home from work to find my two feline companions waiting for me by the door, meowing and purring, prancing across the room because I've come back for them (or you know, for food, whatever).
And later, when your cherished pet brings you a sock all the way from upstairs as an offering, she's made her own pilgrimage, in a way. To my cats, I'm a two-headed cow, too.
