There is no ultimate truth, no absolute to be understood, no "way". God is a construct of religion dependent on specific cultures, so cannot be taken as an expression of any absolute or truth - just one particular culture's idea of it. But just because no particular book or philosophy points to an ultimate truth does not mean we can't find help in the writings of others, writers or thinkers who have experienced and contemplated life experiences - usually painful, or difficult, which are the ones we need help with. To take the teachings of the Buddha, or any Zen master, or Jesus, or whoever, as the correct way to live life is a mistake, and can lead to problems, both personal and societal. But we can benefit by extracting some wisdom from their teachings that may offer insight into our current situation, or may alleviate our suffering a tiny bit, or help us better understand and deal with the difficulties of life.
