The second jewel of the dharma has several implications depending on how the word is used. Sometimes it means the enlightened writing and teachings of the Buddha and sometimes it means the whole phenomenal world. This moment is all we have. This is it. It s not somewhere else or some other time.
All time is right now.
So this moment is a dharma gate we can walk through. It is the gateless gate of no entry, no path, no goal, no attainment. When we wake up to this dharma gate, we experience the radical nature of impermanence. Each moment is different. There is no abstraction here.
