Four Immeasurables, Loving Kindness Part 2

sems can is sentient being(s), thams cad is all, sarva in Sanskrit. So the line starts with the object of all sentient beings.
For those who want to learn the letters, the first letter after the long stroke, shah, is the letter sa, but the long line above it turns it into se, the line on top means an e-vowel. Tibetan does not have any vowels per se, rather the letters are ornamented with signs that indicates the vowel itself.
