If things like Tia Chi give any benefit to your life energy or whatever, you have to explain what that benefit is. If there is a benefit, it must manifest in some physical way, or how else would we know there is a benefit. There MUST be some effect. If must be detectable in some way.
If there is an effect, you also need to explain how that effect is different than normal exercise, or getting a massage. Doesn’t jogging everyday help my body as much as Tia Chi, does stretching and getting a massage relive stress the same.
If there is no difference, then why do we need the concept of life energy. If jogging is the same Tia Chi, then isn’t it more likely that Tia Chi is just exercise, not that it invokes some magical wellness.
If there is a difference, you also need to make sure that difference isn’t just the placebo effect. Like, people think they feel better after Tia Chi because they think spiritual exercise must be better than regular exercise.
If it isn’t placebo, then there must be some measured effect. Again, this effect should manifest itself in some way. This way must be detectable. Meaning we should be able to stimulate the life energy, and get results.
Despite being around for thousands of years, no one actually seems to be able to say what the life energy is or does. We don’t know if it actually exists.
Ask yourself this: How would you know the difference between life energy existing, and you just wanting it to exist?
