Marīcāsana B, a variation of Marīcāsana A, involves placing one foot in padmāsana. For those who have stiffness in the hips or knee pain, yoga master Sharath Jois offers some alternative variations to this pose. By practicing the preceding poses in the Primary Series, the hips will gradually become more flexible allowing you to attempt the full pose. Once you have progressed, it may be possible to lift the padmāsana foot higher and place the heel directly on the navel. In this case, the heel will press back into the abdomen as you fold forward.
