As stated in the beginning of the ÅšrÄ«mad-BhÄgavatam, everything emanates from the ultimate source of the Personality of Godhead; it is therefore understood in this verse that medical science or knowledge in medicine was also inaugurated by the Personality of Godhead in His incarnation Dhanvantari, and thus the knowledge is recorded in the Vedas. The Vedas are the source of all knowledge, and thus knowledge in medical science is also there for the perfect cure of the diseases of the living entity. The embodied living entity is diseased by the very construction of his body. The body is the symbol of diseases. The disease may differ from one variety to another, but disease must be there just as there is birth and death for everyone. So, by the grace of the Personality of Godhead, not only are diseases of the body and mind cured, but also the soul is relieved of the constant repetition of birth and death. The name of the Lord is also called bhavauá¹£adhi, or the source of curing the disease of material existence.
