If the third path happens in minutes, traveling the entire length of the fourth path may take you a lifetime or more.

This is a period when, by tradition, the physical practices of yoga are very important: working from the outside in, as well as the inside out. Banging on the outside of a blocked pipe to clear it, as you push a stick down the inside at the same time. Working to loosen the choke hold of the side channels, the misunderstanding of subjects and objects: ourselves and our world.

At this point we possess the tools for working on the storehouse, but our work is still imperfect. The work itself can trigger minor explosions in the interim, like clearing an old minefield. We encounter obstacles, but we have seen how the end will be, and there is no despair.

Say you meet an angry person. How much longer can you get upset, knowing first that you have created him; and second that your old, natural reaction is precisely the one that will keep him in your world?

So first the negative emotions go, and then gradually all the seeds related to them—all killed by sheer understanding.
