Advice Needed on these 2 youtube videos please

So I have chronic anal fissure for 3 years now. I have a VERY tight sphincter!

These 2 videos on youtube,

I would be grateful if you could answer these 2 questions.

  1. What book can I find them in?
  2. What are the names of the Pranayama exercises?

God Bless and thank you in advance for taking the time to reply. Fissures are a horrible condition so i really appreciate any help.
