The letter SA is the 28th letter in the Tibetan alphabet. It’s energy is feminine. It is also a word meaning “the earth, soil, land.”
In general, there are two kinds of Tibetan script found in print. One is a cursive script called umé. The other, shown here, is called uchen. The uchen letters all have a horizontal line at the top of the letter. This horizontal line is referred to as ‘the head’ of the letter. The head is always drawn first. Then, the letter is drawn from the left to the right, and from the top down. Letters which contain loops are exceptions.
