dhanvantarir bhagavan patv apathyad
dvandvad bhayad rsabho nirjitatma
yajñas ca lokad avataj janantad
balo ganat krodha-vasad ahindrah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
May the Supreme Personality of Godhead in His incarnation as Dhanvantari relieve me from undesirable eatables and protect me from physical illness. May Lord Rsabhadeva, who conquered His inner and outer senses, protect me from fear produced by the duality of heat and cold. May Yajña protect me from defamation and harm from the populace, and may Lord Balarama as Sesa protect me from envious serpents.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
To live within this material world, one must face many dangers, as described herein. For example, undesirable food poses a danger to health, and therefore one must give up such food. The Dhanvantari incarnation can protect us in this regard. Since Lord Visnu is the Supersoul of all living entities, if He likes He can save us from adhibhautika disturbances, disturbances from other living entities. Lord Balarama is the Sesa incarnation, and therefore He can save us from angry serpents or envious persons, who are always ready to attack.
