Is meditation a STS act?

[Agua del Cielo]

I think it would be beneficial to differentiate between working FOR the self as opposed to working ON the self.
I would say meditation as well as healing work done unto the self is a prerequisite for sto.
Everything deep inside of us that is not yet healed could easily result in distorted service.
Or rather in distorted perception of ones service.
Alot of so-called "service to others" is probably done out of egoistic motives.

My personal experience with this was for example, I would "offensively assist or help" my partners in healing and developing. But years later I realized my main purpose in doing this was that I wanted to "create" a partner that would love me unconditionally and assist in my healing.

Another example would be: a friend of mine would always bless the places or locations in nature that we were and do healing work for this particular place.
At the same time he was heavily radiating energy like anger, fear and so on.
Healing work on his self would have stopped him polluting the surroundings with strongly negative energy.

I think, the work we do on ourselves like meditation and healing work, when done with the background of a positive polarity is indeed an sto act.
When meditation is practiced with the intention to control and gain power to control others it would be an sts act.
