A philosophic approach to the question of "after physical life, consciousness continues?":
If one has awareness post-passing, then...there is life after the death process. This awareness ~ = ontological certitude a la Descartes: "I am, therefore I know I am." That possibility ought inspire the philosopher to develop her Cartesian prowess.
If one has no awareness/no being post-passing, then...it's "lights out, nurse." In this "no God, no immortal Soul" scenario, there is also then of course no knowing.
Thus, a bifurcate choice: either there is (eventually, in many cases, after a period of increasingly clarifying "dream"-like "de-sedimentation," as the German philosopher Christoph Turcke/Tuercke terms the clarification process, albeit in a mostly-this-world consideration) lucidity, then the increasing ability to maneuver by conscious intent, akin to soul travel or out-of-body travel for the embodied, and increasing ability to blaze through phantoms of erring e-veiling, both of the dearly departed, and of nefarious forces that seek to amplify the "sedimentation" or untransmuted energy records, unto the Second Heaven and Schools of Light, where Saints and Angels are thus able to minister, guide, instruct, and heal the soul with that sufficient strength to rise to that "transfiguration and resurrection," or there is the "void," aka Nietzsche's "eternal return" as the atom-cards are shuffled in many a universe's creation.
Further in the philosophic genre, there is a Pascal's win-win wager which logically obtains: insofar as meditation, prayer, and such energy-enhancing processes bring social worth to the individual and society, a win (e.g., 10 Commandments as a reasonable guide for conduct 😇); the clarification of awareness also assists in bringing better, brighter dreams, better lucidity (function of integration of conscious and waking subconscious), and even increased dream-time ability to solve problems (this of course may be in part a function of asking Angels and Saints to assist), and even experience bilocation or other siddhis 😊 .
