So correct me if im wrong samatha and vipassna are the goals of all forms of meditation. Anapanasati can be either for the goal of samatha or vipassana (or both). Vipassana is very cognitive, contemplative, and samatha is often the exact opposite, one pointed focus?
Im curious how it works. How does it connect to doctrines of tanha and clinging? Is the samatha concentration lead to deep state of non-reactivity? Like this is how it leads to tremendous results (samatha anapanasati is the meditation used in psychotherapy as just pure stress reduction) . But despite it's results it's not sufficient for the Buddhist path because serious stages of enlightenment require real understanding and insight.
And vipassana on the other hand from what i understand is for insight. it doesnt mean tranqulity and mental strenght cant come from it, in fact the true peace and strength does come from understanding eventually, but thats not the point. vipassana on death is generally not that happy go lucky an experience...
So while insufficent samatha is a good powerful tool for overcoming barriers? If someone is consumed by hatred or anger or anxiety or impatience and they are too frenzied to really practice so it would be good to tranquilize them first? If I'm dealing with a lot of stress samatha would be the place to go?
Tell me if everything I've described is correct. :) thanks
