PURPORT

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.
