The third practices is:
By avoiding bad objects, disturbing emotions gradually decrease
Without distraction, virtuous action nationally increase
With clarity of mind, conviction in the teacher arises.
Cultivate seclusion--This is the practice of the Bodhisattva
That sounds like advice from a Theravadan. The cannon of Mahayana texts comes after the word of the Buddha, though they says they are part of it. It is riffing off the life of the Buddha, combating a sort of isolating self spiritual pursuit. The Bodhisattva goes for Enlightenment with everyone.
Today we have all the texts and don't have to be sectarian, there is one dharma. It's a false dichotomy arhant/bodhisattva. One needs to retreat at times and develop with practices.
There's a group on Facebook called Western Buddhism. People ask questions and post logical conundrums. I want to ask people what their practices are, what do they do, and does it work and how it works.
I have gotten nothing but the culture that if you want to criticize someone, look at yourself. It does not behoove your practice to criticize others. Anyway, we can only control our spiritual lives. Energy invested in progressing yourself instead of criticizing others, is the ideal. It's not that we can't comment on others practices. It's just more like frivolous speech that it is harmonious speech.
