Get Help from Gnostic Teachings

I bought "The dayspring of youth" by M, and in this he advocates:

1. Sing the note F# for 'the length of a breath' for health against cancer
   
2. These myriad workers - whom we neither heed nor help - are often discouraged and seemingly helpless through our excesses in stimulants and labour. The student can encourage them every morning by this exercise: take a deep breath, stand upon the soles of the feet, pat the tip of the liver- the Robin Goodfellow of the Yogi - and send love and encouragement whilst doing so.
   

Are these advised? Also, Where does the tip of the liver resides? From anatomic picture, I would guess at the left of the body, right under the thorax.Also, Master Samael writes in several places:I: Clairvoyance, middlebrow, note TIE: Occult ear, larynx, note SOLO: Intuition, heart, note FAU: Telepathy, solar plexus, note MIA: Memory of past lives, lungs, note LAIs it useful to sing the mantra's using these notes (I guess the Do to use is the one from the piano?).Also, I was unable to tell which note is Ti, is this a Si flat?Thanks for your great support.
