(Īśvarapraṇidhāna): “Uninterrupted devotion or surrender to God,” the final niyama (moral restraint) indicated by Patanjali in the Yoga Sutras. The practice of ishvarapranidhana purifies the remaining desires in the mind. It also orients the mind towards the Divine, until there is no desire for anything but God. The desire for union (yoga) is all that remains in a mind purified by constant devotion. Read more about the niyama here.
