As a long time mediator and occasional consumer of mental health services, I share your concern. I find tremendous benefit in embracing the Buddha’s path as a whole, not picking and choosing based on my own cultural filters. It is hard for me to understand the benefit of amputating one small part of the Buddha’s teachings and practicing that exclusively.
On the other hand, I cannot begrudge people doing something that is helpful to them. As a professional, have you seen any hard evidence that this sort of thing works?
Happy, at rest,
may all beings be happy at heart.
Whatever beings there may be,
weak or strong, without exception,
seen & unseen,
near & far, born & seeking birth: May all beings be happy at heart.
Let no one deceive another
or despise anyone anywhere,
or through anger or irritation
wish for another to suffer.
