A note about the profile photo:

My profile photo* is of Tsongkhapa, founder of the Gelug school of Tibetan Buddhism. Poor student of Buddhism though I am, the study is important to me, and Tsongkhapa is among my favorite Buddhist poets and teachers. He is considered an incarnation of Manjushri, the Buddha of Wisdom, who is in turn usually considered the bodhisattva of writing, poetry, and knowledge. Which is why I included him here — another reminder to myself of the things I value.

Also, it’s hard to see, but he’s using the teaching mudra — the position of his hands, which here symbolizes that he’s teaching a lesson, in the same manner that early icons of Christ show his hands in various teaching, blessing, or judging postures.
