You should always read the books in your lineage
What good is that Arjuna who has not read or heard Gita?
What good is a tirthji disciple of modern day who has not read Maha yoga vigyan or devatma shakti or Saundarya Lahiri by Vishnutirthji?
What good is a yogi who has not read Yoga darshan or Gyaneshwari Gita or Yoga Vasistha Maha Ramayana?
What good Is a Sombargiri disciple who has not read Muktashastra or yog Amrita?
What good is a sanyasi who has not read all of Shankaracharya books?
You get my point!
