Tembe Swami or Vasudevananda Saraswati in his Dwisahastri Teeka says through the following procedures diseases can be cured.
पूर्वजन्मकृतं पापं व्याधीरूपेण पीडते । तच्छान्तिरौषधैर्दानैर्जपहोमसुरार्चनैः ।।
Sins commited in the previous births trouble in the form of diseases (in this life). These diseases can be cured by medicines, charity, japa, yajna and prayer of devatas.
I never knew that there are Yajnas which are capable of curing diseases before reading this. I would like to know the name of the Yajna which can cure diseases.
