Meditation has many techniques. Similar to how people have many different motivations and programs when they have a regular gym practice.
Strength is different to agility is different to flexibility.
In more formal traditions the focus on breath (or similar) is to develop concentration/samatha/samadhi.
The focus on sensations is the insight/vipassana component, and often this is where the tension bubbles up to the surface. Keeping calm (equanimous) during this process can indeed be non-trivial!
It sounds like you have come to a practice very similar to a lot of the Burmese traditions of insight meditation, which is quite fascinating.
Thanks for the pointer. Augurs looks really promising.
If the matrix profile method was included it would be a nice alternative to the numba jit methods that are commonplace.
It does convolution of each sub sequence across the series length, and then shows the distance of the closest match.
This can detect both outliers (long distance from closest match) as well as repeated patterns (short distance).
Pandas is ok for numerical, but Polars (rust-based) is absolutely the way to go for big datasets.
The article is fascinating if you're a Python developer and you need to stray off the path of things Polars can do.
