It is possible to make your own meditation cushion! I purchased colorful felt from Fukushi-center in town and stuffed it with a small pillow. It is washable and removable as well. During asana, this cushion makes difficult yoga positions more achievable. When you take a sitting position during meditation, this cushion elevates the rear and extends the spine. That way, your legs and feet are less likely to fall asleep as you fall deeply into a meditative state. Handmade seat cushions are quick and easy to make and I highly recommend them!
