Hi,
I am the 'Thau' mentioned in the recommendation below. My two cents is as follows:
1. Subtle energy and consciousness-raising technologies should be used only after one is performing regular physical exercise, seeing an excellent psychotherapist, performing cognitive training and actively engaged in daily, healthy spiritual work that includes proper meditation. The above have much better cost-benefit ratios for self improvement.
2. Subtle energy technologies simply create opportunities. They do nothing on their own. Occasionally, you can get a device that will say biologically or psychologically affect a horse but this is exceptionally rare.
3. The proper way to utilize a subtle energy device is to work with it a little while and then put it aside and actively try to duplicate what it does yourself. Go back and forth as many times as possible. Most other approaches turn them into energetic and psychological crutches.
I hope this helps!
