g.yon and g.yas

These two words are good to learn, g.yon means left, and g.yas means right.

Notice the weird way of spelling Wylie. The dot indicates that the ya letter should not be stacked, instead placed after the ga letter. In ACIP formatting this looks like G-YON and G-YAS. If this is not indicated, it is assumed that the ya letter is stacked below the ga letter.

I think we should look at other direction words next. You encounter a lot of such words, especially in tantric text and commentaries where placement of meditational objects are described.
