As a lifelong martial artist and "kung fu" type , during my decrepit old sojourn on this planet, I have experimented with many western-eastern practices like these . There is at the heart of most of this commonality in methodology. Various threads on breathing, yoga , mindfulness movement and all things optimum health and "energetic" have come and gone on RT forum.
It's a natural enough question to ask others if they have done similar and what was their experiences but without sounding too abstract, that's their experience, not yours .
You need to find out what your experience will be in this material . If I were to tell you I reached the 7th level of xyz that was my experience it may not be yours. Similarly if another posted ( and they have) it's all a crock of woo woo shit that's their experience or non experience opinion, not your discoveries.
So I say enjoy your studies as an ongoing self experiment of one. Remain as objective as you can and see for yourself what you get out of it. For you surely have already an idea of what it is you want or hope to get out of it ?
The pdf you posted is interesting in the methodology of layering components , for example, if I am learning new movements I have to do as the pdf advises separate to combine. Let's take for example the correct knee alignment mentioned but let me shift the context. My training partner getting his fencing sword lunge incorrect with a foot knee position that in long term will rip his tendons to bits and destroy his ankle knee . Well, I have to deconstruct every small micro detail and get him to do each part at a Hong Kong octogenarian super slow motion play speed...however, once learned and internalised he can pick up the pace speed to higher faster intensities to all out max speed.
Sometimes I will go down to the beach and in front of the ocean when no one is around and use what you might call a super slow synchronised totality of "moving meditation" when wanting to learn new sword skills. So that little by little it gets internalised to greater speeds. Be it this your studies or kundalini yoga or Russian autogenics , Tibetan kum nye or the 5 tibetans, yoga nidra, auto suggestion, lymphatic movement or any other of a million practises to "optimise" you for a quality life, then it's worth exploring in an increasing media neurotic three ring circus of modern life . Even if it serves as a useful support chapter for that part- time period of your life or to satisfy the exploratory mindset and answer your questions about it . ( as long as it isnt harming you or others in some way) The practises I did in my robust bulletproof 20s are not the same as a greying haired 57 year old ... they got dropped, changed, adapted as my needs changed or my philosophy of approach changed.
Interesting post , good to ask as many of the old timers on this forum do experiment and add subtract , switch up and switch out their practices.
