Buddhists especially laybuddhists must not conduct this mistake.
Unless laybuddhists have already attained, otherwise, there is no
basis for condemnation of other traditions or sangha. Depending on
your affinity and aptitude, rest on the practice and be truly in
compliment of others buddhism schools and sangha as well as
monkhood, this is for a larger context of buddhism teaching. This
will greatly assist the journey in the ultimate goal of buddhism
teaching. Just an example, if let say, pureland buddhist speaking
ill of a monk, but Buddha Amitabha was a monk called Dharma Store
who developed the pureland prior to his fruition, so illing against
monk is self explanatory. Either buddhists or non buddhists causing
schism in the sangha, the self damage is extraordinary large. May
the blessment of buddha be with all
