In this profound verse, Dr. Sharma compares a true astrologer to a master physician.
In medicine, if a doctor correctly identifies the root cause of an illness ("pakdi jaye nabz"), even a terminal patient can be saved. Similarly, in Lal Kitab astrology, if the astrologer correctly identifies the exact planetary affliction causing your problems, a simple remedy can fix your entire life.
But if the astrologer misdiagnoses your chart and gives you the wrong remedy, it will act like the wrong medicine. It will destroy your good Karma, and your "awakened destiny" will go to sleep. This is why you must never perform random remedies found on the internet.
