Hexagram 57: 巽

Change through gentle, persistent influence. Not force—flow. You're building something that changes behavior. A system, a workflow, an organizational process. The temptation is to mandate it. Big rollout, required adoption, top-down decree. That's force. It creates resistance. The classical text and Doug McIlroy both say: wrong approach. Lasting change comes through small, consistent, well-designed interventions that people actually want to use. The UNIX tools succeeded because each one solved a real problem elegantly. People started piping them together because it worked better than alternatives. 'cat file.txt | grep pattern | sort | uniq'—each tool penetrates the data stream, processes what it needs, passes the rest along. The behavior spread through demonstrated utility, not mandate. Penetration through gentleness means: make the new way obviously better for small tasks first. Let people discover it solves their immediate problems. Let the behavior spread through word of mouth, through people showing each other the better tool. This takes longer than forced adoption. It also actually works. Forced adoption creates compliance. Gentle penetration creates genuine change. Here's the implementation pattern: start small. One tool that does one thing well. Make it excellent. Make it genuinely easier than the old way. Let early adopters discover it. Listen to their feedback. Improve it. Build the next small tool. Make them work together. The pipes emerge from use, not from master plan. The failure modes: impatience (trying to force adoption before the foundation is ready) or the opposite (deliberating endlessly without deciding—the text warns: 'Repeated deliberation brings fresh doubts and scruples, and thereby humiliation, because one shows oneself unable to act'). Decide. Build the small thing. Make it excellent. Let it work consistently. Then build the next small thing. Time is the instrument. The wind that keeps blowing eventually reshapes the landscape. But it does so through ceaselessness, not through occasional hurricane force. The UNIX pipe succeeded because it was gentle, composable, persistent. Each tool transformed the stream slightly. The cumulative effect was profound. But no single tool tried to do everything. That's the pattern: gentle influence, small pieces, sustained over time. Not dramatic revolution. Gradual penetration that becomes complete.
