tanmayo bhavati kṣipraṃ jīvabrahmaikyayojanāt |
athavā samalaṃ ceto yadi kṣipraṃ na siddhyati ||

If one does not quickly do this, owing to impurities of heart, then the Yogi ought to adopt what is called the "Avayava Yoga." O Chief of Mountains! The Sâdhaka should fix his heart on my gentle hands, feet and other limbs one by one and try to conquer each of these places. Thereby his heart would be purified. Then he should fix that purified heart on My Whole Body.
