"If you want to know how to climb the Golden Ladder to Heaven, I will tell you how to do it. Love. Simply love. Every step of love is a rung up on the ladder. Of course, there is no distance when it comes to love. Love is immediate. It takes no time at all."
what is the meaning of "a rung up on the ladder"?
Thanks
