Stoicism

Philosophy does not promise to secure anything external for man, otherwise it would be admitting something that lies beyond its proper subject-matter. For as the material of the carpenter is wood, and that of statuary bronze, so the subject-matter of the art of living is each person's own life.

--Epictetus

To embody vastness

Whenever something comes up in our mind, which causes suffering, it is to look at it squarely and say "not just this" and then we expand, just a little bit. Make this a way of life and we keep expanding, a little bit at a time, and who knows where that might lead.
