My long opinions about attempts to mix buddhism with postmodernism are in this topic starting page 59: Ven. Ñāṇananda, Nibbana and Phenomenological Existentialism - #60 by dxm_dxm
The only way to read the suttas comprehensively is through jhanas. With jhanas not only they understand but it is not necessary to look for them … they come alone.
The Jhana that the historical Buddha taught is not some form of banana jhana. Those who achieved jhana in the sutta quickly achieved non returning. (ZERO sensual desire, ZERO aversion) Jhana is not attained by doing some exercise, it is something that comes out of seclusion. It’s quite difficult to achieve it as a layman, though it’s probably possible if one has the lifestyle of a monk. But it takes a lot of time. B.Bodhi for example has said he never achieved it. It takes real renunciacion to achieve. Check MN 39, MN 107, MN 125
And about matter not existing and the world been an ilusion, etc. These solipsist/philosophical idealism/ illusionist ideas are not what Buddha taught. Buddha taught something different, something subtle, something that can not be understood without reading the sutta pitaka. It’s easy to confuse Buddha teachings to be materialism or idealism or postmodernism. But they are something different, something difficult to grasp.
