Easy Padmasana (Sukhasana) can be practiced when you cannot and do not practice Lotus pose. We generally sit on this pose on the floor in informal situations. There might be someone who cannot practice Lotus pose due to some knee joint problems, etc. Your legs should be kept in a position so that it becomes helpful for the spine to remain in a comfortable and natural posture. This is helpful for any other yoga practice based on it and mindfulness meditation as well
One can sit for a longer duration in this pose. More suitable for those having knee joint problems. Also suitable for the higher age category.
