Occam’s razor can be used quite effectively to cut through bs that one will invariably have to deal with in spirituality.
A general rule of thumb I found to be effective is that any spiritual teaching or system that overcomplicates it’s understanding or practice is less effective than another which employs less complexity.
The materialist model of reality is the most complex of all models out there. This employs lifeless matter organizing itself into complex patterns which mysteriously come alive and produce consciousness.
On the other hand the traditional Spiritual eastern models of reality almost all suggest that consciousness is the basis of the universe and matter merely appears and disappears in it.
IMHO the eastern models are less complex and require less assumptions. On that basis, the materialist model is less likely to be ‘correct’.
