Dude! Seriously? Who are these Theras you refer to? And how did you go about examining them? Basically there are two types of cultivation. 1. Jhana and other onepointedness exercises that are for getting control of the mind and sharpening it as you would a pencil before use. 2. Bhavana that developes and deepens your understanding of the Dhamma. There is no patchwork, no quilt and absolutely no plaid. I think Element has provided ample references. /Victor
