In materialistic life, there are cases where an Ophthalmologist suffers from eye ailment, a Cardiologist suffers from heart ailment, a Psychiatrist suffers from mental disorder; however, in Spirituality, Saints do not suffer from spiritual distress after curing others of their spiritual distress. Some Saints do suffer from physical ailments; but, they are as per their body-prarabdha and does not effect them.
