Namaste Silverbackman,
thank you for the post.
indeed, the methods of meditation are common amongst the various Dharma traditions... as we Buddhist types would term them, Vipassana and Samatha.
you are, of course, correct that the purpose of such meditation is different between the Sanatana Dharma and the Buddha Dharma.
so... it sort of depends on where one is in their practice on what they are using the tool of meditation to do.
for some beings, the meditations are used to realize the Wisdom of selflessness, in others, the meditations are used to increase ones Compassion and lessen the obscurations in the mind.
if, for the sake of discussion, we must choose a "goal" for Buddhist meditation, then i would say that "goal" would be the attainment of Buddhahood.
metta,
