Wonderful wonderful Lojong here!
“Be Grateful to Everyone” is such a positive admonition. Kongtrul, in his older version of these slogans, renders it as “Contemplate the great kindness of all.”
This is part of the ‘poison as medicine’ theme, or Transformation of Bad Circumstances as it’s called in Trungpa’s rendering. In this theme, the idea is that all the people and events of our lives are things to be thankful for because they are what provide us with the opportunity to practice, to follow the path, which means the opportunity to get beyond self.
Without all these apparent ‘obstacles’ in our lives, there is no path, no way to proceed on the project of developing patience and compassion, ways to transcend our normal ego-centered, reactive approach to everything. The contemplation of just how indebted we are to the others around us becomes a major part of each meditation, as well as an important piece of the mindfulness that helps us to get through the day without stressing ourselves and the others around us.
Becoming able to actually feel gratitude to someone who has hurt you or caused difficulty for you, intentionally or not, is a great transition in life. It’s not easy and it doesn’t happen in a short time, but with patience, it will come. It just takes ‘practice!’
This Lojong slogan is very close to the Christian idea of “Praise God in all things” as well as the Chinese notion of ‘disaster as opportunity’.
