“Come, come, whoever you are,wanderer, worshiper, lover of leaving,it doesn't matter.Ours is not a caravan of despair.Come, even if you have broken your vow a hundred times.Come, come again, come.”

Rumi: Jalaluddin Rumi was an ancient Persian scholar and Sufi master. Today he is recognized as one of the greatest poets who ever lived, due in part to how his words seem to speak to the divine

I am always holding a priceless vase in my hands. If you asked me about the deeper truths of the path and I told you the answers, it would be like handing sacred relics to you. But most have their hands tied behind their back; that is, most are not free of events their eyes have seen and their ears have heard and their bodies have felt. Most cannot focus their abilities in the present, and might drop what I said. So I’ll wait;
I don’t mind waiting until your love for all
makes luminous the now.
