Q156. What is the difference between Devotees and Yogis?

Yogis are those who are only interested in their own advancement, they have no interest in helping others to advance. Devotees are those who help others to advance, they don’t think about their own advancement. Basically, devotees want to save others and yogis only care about themselves. Arjuna was a pure devotee and thus we should become pure devotees and not pure yogis, verses 18.68-69 confirm this.
