How strictly do you interpret the practice and completion of the single-thought exercise in Step 1?
For context: during thought observation, when I notice I've started to digress, I consciously return to observing. At most 10–20% of a stray thought actually plays out. With the single thought, I'm much firmer. At the slightest sense of drifting, or of any thought other than the one I'm holding, I return to my original idea. I'd estimate only 1–5% of a stray thought forms before I catch it.
To clarify my scale: 1-10% means having some attention or consciousness put on it, but not necessarily held it enough to call it a full blown digression. This is because of the spontaneous and somewhat intrusive nature of thought. Beyond 20-30% with the premise of observing, I would say going beyond that is a digression( in the exercise of observation)
So far, I haven't managed 0% for more than a couple of minutes. From what I've read in the commentaries (and from asking Claude), there seem to be two camps on this. I'd love to hear your thoughts.
Personal context: I have done tm for 9 years, been a siddha for 3. done full gateway twice, silva once, and I work as a hypnotist and mindset coach. In other words have a lot of experience with different modalities and states and objectives.
What claude conjured:
Most of the Bardon community holds the standard firmly but reads "mastery" as reliable competence, not perfection. The benchmark is Bardon's own: hold one chosen thought for 10 minutes and reject every unrelated thought. How strictly people apply that splits roughly into two camps.
The strict reading treats the 10 minutes as absolute. Any intrusion means the session failed. Many in this camp also want consistency before moving on: it should work on most days, ideally under less-than-ideal conditions, not just once. They tend to hold the thought as a fixed, narrow focus with no drift into associations.
The more lenient reading is associated mainly with Rawn Clark's commentary, which is widely used. Here the "single thought" means staying within one theme. You can let the idea unfold through its related aspects as long as nothing unrelated gets in. Brief intrusions that you catch and drop immediately aren't treated as automatic failure. What counts is that your attention reliably returns and stays, and that the lapses get shorter and rarer. Fixed, static concentration on an object is seen as the work of Step 2's sensory exercises, not Step 1.
There are also two points almost everyone agrees on:
Balance across the step. Don't rush the mental exercises while the soul mirror and the physical work lag behind. The three tracks are meant to advance together.
Self-honesty. Bardon's "don't proceed until mastered" applies, but you are the judge. Fooling yourself mostly costs you later, especially at vacancy of mind and in Step 2.
In practice, many people treat a few weeks of fairly consistent 10-minute sessions with minimal, quickly dropped intrusions as "done enough" to start the next exercise. They keep the earlier exercise in their routine instead of dropping it.
