Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
After finishing this chanting, one should think himself qualitatively one with the Supreme Personality of Godhead, who is full in six opulences and is worthy to be meditated upon. Then one should chant the following protective prayer to Lord Narayana, the Narayana-kavaca.
