Should I use a timer when I sit? Some people say set an alarm; others say sit open-ended.
The short answer: timers are allowed but optional, and they have exactly two legitimate jobs — ending the session and protecting the schedule — and one illegitimate job: measuring progress. Use a timer if it removes clock-watching; drop it if it becomes a finish line to stare at. The classical tradition’s answer is simpler: sit until regulation breaks, not until a bell rings.
What the tradition actually says
- The manuals have no clocks. The Xiao Zhiguan regulates body, breath, and mind — and re-checks them before, during, and after — but prescribes no duration. The unit of a classical session is the breathing cycle: “expel stale breath three times,” then regulated breathing; the session ends when the regulation does, not when time is up. The site’s duration question states the same principle from the other side: the tradition’s measure is the quality of regulation, not the minute.
- The archive’s version, verbatim in paraphrase. The Taishi collection’s lotus-posture chapter answers a reader who split a one-hour sit into two pain-relieved halves: useful — at the beginning everyone endures it that way, and in the end it all opens (有用！一开始都是那么熬过来的，最后都能通). And to another reader: sit every day until you cannot hold it — the time doesn’t matter; if each session is short, sit twice, morning and evening (打坐每天坚持到坐不下去就行了，时间不重要；每次时间很短，那就早晚练两次). The archive’s rule is a body-signal, not a number — and the site files it as the practitioner-world counterpart of the manuals’ regulation: the session’s end is a quality, not a quantity.
- The one classical warning applies to the timer itself. The tiaoxi frame — harmonize, never force — covers the clock too: a timer that makes you hold a collapsing posture until the bell is the opposite of the method. A timer that frees you from looking at the clock is fine; a timer you fight is a forcing device wearing a neutral face.
The modern cases, both stated
- For a timer: it ends the session so the rest of life can proceed; it removes clock-anxiety (“how long have I been here?”) from the sitting; it makes the daily habit concrete, and the site’s habit question notes that regularity — not length — is what keeps practice alive. A soft alarm (a bell, not a phone buzz) set for the minimum is the standard beginner’s scaffold: sit the minimum, then stop, or continue if regulation holds.
- Against a timer: it installs a finish line the mind can watch for — the community discussions this site draws on (anonymized per the privacy rules) report that clock-watching, including timer-watching, is one of the commonest early distractions, filed on the restlessness page; and an alarm that interrupts a good sitting teaches the wrong lesson, that the session’s length is its value. The tradition’s alternative is the archive’s: sit until the body or mind genuinely breaks regulation — then stop, without self-judgment.
The one rule that matters
Do not let the timer measure progress. The tradition’s measure is stability (progress page: months of the same practice, not states); the archive’s measure is the body’s own signals. A rising timer — “last month 20 minutes, this month 25” — converts the sitting into a race against the clock, and the site’s records are consistent that the race is what breaks the practice. The timer ends sessions; it does not grade them.
