There is no one correct way to sit on a yoga cushion while meditating. A lot will depend on the style of yoga you are doing or if you are meditating or trying to learn a new pose. The round zafu meditation cushion is perfect for helping with the Lotus or half lotus position, which is a common meditation position that everyone starting out in yoga hopes to be able to achieve one day. Using a cushion to help support you is a great way to retrain and expand the muscles and flexibility of the hips. In full lotus, you are sitting cross-legged with your feet resting on the opposite inner thigh. This may seem impossible when you first start your yoga practice, but the more you do, the more you will increase your flexibility and make it easier to achieve any pose that challenges you. The beginning phase of the lotus is Sukhasana, which is often called the easy cross-legged pose. This is how we all sat as children in the assembly halls with our legs neatly crossed but feet resting on the floor rather than the more advanced pose of lotus where they must rest on the thigh. Again, your yoga meditation cushion is perfect for this exercise, and by sitting on it, you create more space on the floor for your legs to cross if this does not feel very natural at this point. If you have a square meditation cushion, you will find it perfect for supporting in positions where you are resting your weight on your knees or ankles. Experimenting with placing a cushion in various different roles will help you find the most comfortable way to support the body and therefore extend your yoga practice.
