I came across a lovely Buddhist story about overthinking and getting carried away.
There were once three monks on a pilgrimage. Two of them were young, novice monks, while the third was an old, experienced one. On their journey, they came across a river. As a consequence of last night's deluge, the currents were fierce, making it nearly impossible for ordinary people to make their way across. The monks' training involved mastering their bodies in conjunction with their minds; through some effort, the impediment could be overcome.
Just as they were preparing to commence their journey across the river, they saw a beautiful young girl coming their way. She entreated them to carry her across the river to see her ailing father, but the monks had vowed never to touch a woman in their life. The young monks informed her of this, but the girl was adamant about crossing the river. At that moment, the old monk offered to carry her, which she gladly accepted. After dropping her off on the other side, the monks continued their journey.
The young monks couldn't believe what their teacher just did. He had broken one of their most sacred vows; how could he do it casually like it wasn't a big deal? The thought troubled the pair for a while, and about 30 minutes later, when they could no longer suppress their thoughts, they demanded an explanation. The wise old monk said:
"I dropped her off 30 minutes ago. You are still carrying her."
