These helped me a bunch just now (being upset myself):
When a person lives heedlessly, his craving grows like a creeping vine. He runs now here & now there, as if looking for fruit: a monkey in the forest.
If this sticky, uncouth craving overcomes you in the world, your sorrows grow like wild grass after rain. If, in the world, you overcome this uncouth craving, hard to escape, sorrows roll off you, like water beads off a lotus.
If its root remains undamaged & strong, a tree, even if cut, will grow back. So too if latent craving is not rooted out, this suffering returns again & again.
Encircled with craving, people hop round & around like a rabbit caught in a snare. Tied with fetters & bonds they go on to suffering, again & again, for long. So a monk should dispel craving, should aspire to dispassion for himself.
Cleared of the underbrush but obsessed with the forest, set free from the forest, right back to the forest he runs. Come, see the person set free who runs right back to the same old chains!
That's not a strong bond — so say the enlightened — the one made of iron, of wood, or of grass. To be smitten, enthralled, with jewels & ornaments, longing for children & wives: that's the strong bond, — so say the enlightened — one that's constraining, elastic, hard to untie. But having cut it, they — the enlightened — go forth, free of longing, abandoning sensual ease.
Those smitten with passion fall back into a self-made stream, like a spider snared in its web. But, having cut it, the enlightened set forth, free of longing, abandoning all suffering & stress.
For a person forced on by his thinking, fierce in his passion, focused on beauty, craving grows all the more. He's the one who tightens the bond. But one who delights in the stilling of thinking, always mindful cultivating a focus on the foul: He's the one who will make an end, the one who will cut Mara's bond.
