I started essaying on saddhā because I noticed that aspects of my inherited worldview were impacting the amount and kind of effort I was applying in my practice. Some of these metaphysical positions are relevant to the practice, such as belief in kamma, rebirth, dependent origination, but others are not relevant, such as whether the cosmos is infinite in time and space - getting entangled in speculation about these questions is illustrated by the Buddha with the image of the thicket of view, ‘a contortion of views, a writhing of views, a fetter of views’ (MN 72)
