Perhaps it to attempt to attain passadhi (samatha) through vipassana is putting the cart before the horse. Or rather a different kind of insight is called for as a foundation. Yoga citta vrtti nirodha. Understanding the relationship between consciousness and the body - and the existence of a middle subtle body-consciousness field which carries the feedback interaction between both (the neuro-muscular aspect is important). The unified field has some analogy the solutions of Klein-Gordon and Dirac equations (Dirac was perhaps the greatest physicist of the 20th-century).The models of René Thom come very close to the idea of a field of harmonic oscillators over space-time. The goal of the fundamental stage of TPP is to attain the pax profunda, possibly using psycho-somatic feedback as a support (to dampen or muffle the spectrum of mutually exciting harmonic oscillators). What we ordinarily call 'body' and ordinarily call 'mind' are two complementary modes of the same underlying consciousness-field. It is only in the deep clarity and stillness of the mind-body field that authentic TPC can blossom 孰能濁以靜之徐清. Thus the initial TPC involves perceiving consciousness as an excitation and self-interaction (producing the illusory perception of the individual self) of an underlying psycho-somatic field, and understanding the effective dynamics (and functional stratifications ) and feedback mechanisms to attain the desired goal. This initial TPC is indeed the pure impersonal perceiving of the flux of consciousness as thus, but also the inner first-person experience of the body (i.e. we have nama-rupa): it is also the perception of how the inner body generates a kind of frame of reference or proto-space (proto-topology) for the total sphere of consciousness. Temporality is on one hand transcendent and a condition for thought and consciousness rather than being generated by consciousness, on the other hand it is generated as an illusory excitation. We must find the lost original deeper meaning of Pyrrhonism, regarding belief, thought and agitation - the same underlying TPC insight.
Some things to explore: how can the role of symmetry in physics be transposed to understand the central role of symmetry in consciousness ? And in the symmetries in logic ? Philosophically, how can our theory of a priori computability relate to the obviously rich computational nature implicit in the study of solutions of PDEs ? Radiation, diffusion, harmonic equilibrium. Geometric optics. Singularities of the solutions of PDEs such as the Hamilton-Jacobi equation. Meaning is perhaps described as symmetry invariance in the dynamical system of consciousness.
What are sense and reference ? It seems that we can reconcile psychologism and objectivity by a theory analogous to that of the invariance under group actions used in physics. The conscious content for two different people can differ, but the contents must be related to each other through a well-defined law, a continuous symmetry group, a deformation. Galilean relativity has perhaps an immense overlooked philosophical significance. It shows that objectivity is relational (all inertial frames of reference are equivalent, there is no absolute frame of rest), but not less objective for that. Once the idea of group action and group invariance had been brought to light - in physics as well as geometry - it is the most natural thing in the world to investigate hyperbolic geometry (Gauss, Lobachevsky) in this light. Why is the connection of Minkowski space (the pseudo-sphere) to hyperbolic geometry obscured (obtained by the analogue of the stereographic projection of a sphere)?
