“Occam’s razor” principle teaches us to shave away the useless complications when you do not need them. Keep it as simple as possible (but not simpler – would say Einstein).
This reminds me of a story:
Tired of so many years of travel and danger, Nasreddin was wandering back home. On his way he met a Sufi saint. They walked together for many days, in silence, heading for Konya.
At the muddy banks of the Kizilirmak not far from Karalar, the large expanse of the waters halted their progress. For a while, they looked quietly at the peaceful settlement on the other side of the river.
Unexpectedly, the saint spoke: "I can walk on water. It took fifty years of meditation, and now I am light enough. But I can’t take you with me."
The Hodja raised his eyebrows:
"Fifty years? That's a long time…"
Followed another long moment of peaceful silence. Then Nasreddin added:
"Concerning me… why not stroll over to that man with the boat and pay two coppers for the passage, both of us?"
