Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Visvarupa said: If some form of fear arrives, one should first wash his hands and legs clean and then perform acamana by chanting this mantra: om apavitrah pavitro va sarvavastham gato ’pi va/ yah smaret pundarikaksam sa bahyabhyantarah sucih/ sri-visnu sri-visnu sri-visnu. Then one should touch kusa grass and sit gravely and silently, facing north. When completely purified, one should touch the mantra composed of eight syllables to the eight parts of his body and touch the mantra composed of twelve syllables to his hands. Thus, in the following manner, he should bind himself with the Narayana coat of armor. First, while chanting the mantra composed of eight syllables [om namo narayanaya], beginning with the pranava, the syllable om, one should touch his hands to eight parts of his body, starting with the two feet and progressing systematically to the knees, thighs, abdomen, heart, chest, mouth and head. Then one should chant the mantra in reverse, beginning from the last syllable [ya], while touching the parts of his body in the reverse order. These two processes are known as utpatti-nyasa and samhara-nyasa respectively.
