so, the basic question here is something to the effect of---
do i (zoebird) think that life is a series of sufferings in order to receive certain lessons or is it more pleasurable/optimistic than that?
i do not see the cosmos in terms of punishments and rewards, but rather an unconditional love experience. i have inherent value in the cosmos, a role as well, and overall the whole process is to be simple experienced with joy and thanksgiving.
i believe that we cocreate many experiences, and that some experience simple 'happen' to us (created by another. our reactions to what occurs is often what 'cocreates' the experience as either pleasurable or not, and both pleasure and pain/suffering can be personally rewarding and beneficial.
when i am in an experience of suffering, often created by my own reaction to whatever is occurring, then i consider it an opportunity for learning, it becomes an aspect of spiritual discipline--of striving to experience. in pleasurable reaction, it is far easier to experience, but it creates its own lessons as well.
not that this is any more clear than the question. . .i didn't read the whole OP simply because i found it convoluted, and, as a pp mentioned, i also felt like i was being "sold" something rather than invited to participate. but, the question at the end is worth discussing, so i answered that.
