I saw an announcement of yoga. It said:
Learn the basics of yoga in 4 lessons.
In 4 lessons, I thought, I practice decades and do not understand fully the basics. It seems to be a class for fast learners.
(Yes, I know what is meant by it. The imagination that something could be understood in 4 lessons amused me. What is possible within 4 lessons, I wonder. To lick blood, to get excited about it, the wish to go on can arise. This is a lot. And of course some basics can be learned, too.)
Of course I recommend this class, I recommend every yoga class.
