I.23 - īśvara-praṇidhānāt-vā
Patañjali recognizes that attempts to bring the mind to the state of Yoga are fraught with obstacles which vary in potency. But, for those who have either an inborn faith in God or are able to develop it over the years,
Offering regular prayers to God with a feeling of submission to his/her power, surely enables the state of Yoga to be achieved.
