There is currently a discussion going on in this forum about the valididy of a Bifrucated theory of Jhana (i.e. Samatha Jhana and Vipassana Jhana). I would like to be able to participate in the discussion, but I am not sure if I am knowlegable enough about what exactly these terms mean and whether or not they are used with diferent meanings by diferent groups. This is my question:
According to the traditions that classify Jhana into Samatha and Vipassana subtybes, what is the definition of Samatha Jhana, and What is the definition of Vipassana Jhana?
I have heard from some sources that Samatha Jhana is entered by directing the mind's attention to a single distinct point of focus (e.g. Kasina, or the tip of the nose or upper lip as some groups practice Anapanasati), whereas Vipassana Jhana is defined as Jhana that is entered with awareness that is not restricted to a point, but I'm not sure if that is a complete and exhaustive definition.
Can someone give the full definitions, preferably citing sources such as the commentaries, sub-commentaries, Vissudhimagga, or the works of Mahasi Sayadaw? I don't want to end up misrepresenting anyone in discussion.
