Assuming the consciousness that unifies all egos isn't particularly human and has no affiliation with any culture, your mysticism is consistent with the essence of cosmicism. Cosmicism is the view that our perspectives tend to be too narrow because we become fixated on local matters and ignore our role in the cosmic scheme. Mysticism has the same implications.

An atheistic philosopher is free to feel life's absurdity and to have the larger truth thereby shown to her. You're focused on a monistic impression which you can have from meditation. But we also experience life's amorality and the universe's indifference to life on a daily basis. The difference is that the unreflective folks don't have a perspective for putting that wealth of data into a suitable context. Philosophy enables us to understand the big picture, but that doesn't mean philosophers have to be hypocrites or must be sheltered from reality and fixated on academic pseudoproblems.
