Not have having pure vision and devotion cannot received blessing

Therefore, as a Dharma practitioner it is basic thing to have devotion, to believe strongly in the practice. Buddha repeatedly teaches about the importance of having pure vision and devotion. This is true. We can learn that from many great masters, great practitioners. Because of their devotion and pure vision they have reached such high accomplishments. And we can learn from other people that they cannot received blessing of the practice because they do not have pure vision or devotion. So that shows us the importance of devotion and pure vision. So we, Vajrayana practitioners, should try hard to have pure vision and to see the importance of devotion and pure vision.
