Fantastic little workbooks with line drawings on one side of the page and then a blank page on the other -- for your notes, musings or alignment points. They have four of them: Yin, Vinyasa and Ashtanga Primary and Intermediate series. They make nice gifts too!
My favourite nugget of information given in this book by Donna Farhi (although there are many nuggets) is that types of breathing are contagious...surround yourself with peaceful calm breathers!
A book from my days of lecturing in dance, this still has a lot to offer in my teaching of yoga. Beautiful imagery (in a poetic style) and perfect for reading in Yin class. Love!
