Prapadasana is said to be beneficial for memory and concentration, given the focus it requires. Different variations of prapadasana may be sequenced together to enhance the benefits of the posture.
Traditionally, prapadasana is associated with the seventh chakra, the sahasrara. Working with this chakra is said to help yogis experience unity and realize their connection with everything. It can help the yogi to open him/herself up to the Divine while remaining physically grounded.
Some yogis say that the ankles are associated with both tackling rigidity and controlling impulses. As prapadasana does stimulate the ankles, it is thought to help the yogi become more physically and mentally flexible, as well as more in control of his/her animal instincts.
