1. Absolutely Upright

A universe is a particle and a cosmic body formed by countless layers of universes is also a particle. In the future, many sentient beings in the particles of the cosmos will listen to Dafa disciples teach the Fa. Therefore, Master has required us to be "absolutely strict and absolutely upright." (from Master Li Hongzhi's "Lecture at the Great Lakes Conference in North America")

2. External Interference

The concepts of "internal" and "external" held by everyday people are untenable. For cultivators, external interference is in essence directly related to the internal, and is comprised of attachments, karma, notions, etc. With respect to the origin of a life, these things belong to the external; thus, looking within in cultivation practice is actually looking for these "external" things that exist internally and eliminating them completely. If a Dafa disciple has become pure and upright on the inside, then all external interference will cease to exist.

Just my personal understanding and enlightenment; please point out compassionately anything inappropriate.
