Have you noticed that if you really think about it, working on hardware circuits and power development is highly compatible with spiritual practice and becoming a monk.
1. You Have to Learn to Let Go of Obsessions
The most tormenting part of circuit design is obsession: always wanting the perfect topology, hoping component parameters will be exactly right, and insisting that debugging should succeed on the first try.
It’s like letting go of delusions in spiritual practice.
You debug Buck/Boost circuits and MPPT loops. In theory, the parameters are perfect, but as soon as power is applied, there’s oscillation, strange noise, or abnormal behavior under load; you repeatedly measure waveforms, revise the PCB, and swap components.
In the end, you gradually realize that there is no absolutely ideal circuit. You learn to accept tolerances, make trade-offs, avoid forcing perfection, and understand compromise in design. With fewer obsessions, bugs often become easier to find.
2. Long Meditation Sessions = Long, Tedious Debugging Sessions
Monks sit in silent meditation; we sit in front of an oscilloscope, staring at waveforms for hours.
While others unwind after work, you’re still comparing Bode plots, tuning PID coefficients, troubleshooting Miller oscillation, bootstrap negative voltage, and parasitic interference.
Most of the time, there are no immediate results. It’s a long, quiet, lonely process of trial and error. If you can’t stand being alone with it, you simply won’t make it.
3. Look Inward to See the Unseen “Formless Things”
Monks observe the stray thoughts in their own minds;
We deal with the invisible enemies in a circuit: parasitic inductance in traces, distributed capacitance, ground-loop interference, and high-frequency coupled noise.
The schematic may look flawless, only to be ruined by PCB parasitics. You can’t see them with the naked eye; you can only rely on instruments and reasoned experience, much like observing formless thoughts.
4. Let Go of Restlessness and Quick Wins
Switching power supply loops and digital compensators are most vulnerable to impatience.
If you start by aggressively tuning PID parameters or randomly replacing inductors and capacitors, things will only get more chaotic.
It’s like observing precepts: slow down and test layer by layer — first no load, then light load, then dynamic load, tracing the source step by step. Once your mind is scattered, even measurements can go wrong.
5. Everything Is Impermanent; Variables Are Always Present
Buddhism speaks of impermanence and dependent conditions; a circuit is a bundle of “dependent combinations.”
A change in temperature, input voltage fluctuations, or differences between component batches can suddenly cause a stable circuit to fail.
There is no one-and-done solution. You always need to leave margin, think through protection mechanisms, accept variables brought by the environment, and adjust accordingly.
6. A Sense of Solitude
Many hardware problems are hard for anyone else to fully empathize with.
Loop oscillation, EMC non-compliance, and soft-switching failures usually mean you’re on your own, slowly making sense of waveforms. It’s hard for anyone to immediately point the way out.
Spiritual practice is your own affair; realization has to come from within. Others can offer hints, but they can’t cross the difficult passage for you.
But There Is One Fundamental Difference Between the Two:
Monks seek to let go of everything and detach from worldly disturbances;
We practice within the world.
We don’t run away from difficult problems. Instead, we cultivate a steady heart and build a stable, reliable system amid noise, oscillation, and countless failures.
The ancients said, “All worldly affairs are a training ground.” Your oscilloscope, LTspice, and PCB layout software are your meditation hall.
Every sleepless afternoon spent debugging circuits is meditation.
. But you’re right, OP: every time I power up a board for the first time, the silent prayer in my heart—“Buddha, please don’t let it blow up”—is more devout than any high monk’s. Sir, you’ve attained enlightenment. My Buck converter is whining again, so I’d better go perform a rite for it.
But hey, my “meditation hall” (Altium Designer) keeps crashing and giving me error codes, does that mean my karma is bad or I’m failing my spiritual practice? Seriously though, this is a beautiful post. It just proves that the pain and suffering of hardware design are universal across all languages and cultures!
But honestly, after you’ve been in this line of work long enough, your mindset really does change. When I was younger, I could rant for half an hour at a board that had blown up. Now if it blows, it blows; first I cut the power and start troubleshooting, calm and collected. Maybe that’s the “worldly cultivation” the OP was talking about.
