Practice becomes firmly grounded when it is done for a long time, without interruption, and with care.

Three conditions, all unglamorous: long duration, no gaps, and respect for what you are doing. Satkāra — care, reverence — is the one most often dropped, and it is the difference between repetition and practice.

This is the verse to read when a practice feels like it is going nowhere. The text's answer to "how long?" is "longer than that, and don't stop."

"Without interruption" is sometimes read as "never miss a day or you start again". The word points at continuity of attitude, not a streak counter.
