Gatir bharta prabhuh saksi
nivasah saranam suhrt
prabhavah pralayah sthanam
nidhanam bijam avyayam
(The Most Confidential Knowledge, Text 18, Chapter 9)
Meaning: I am the goal, the sustainer, the master, the witness, the abode, the refuge, and the most dear friend. I am the creation and the annihilation, the basis of everything, the resting place and the eternal seed.
Bhagavad Gita: Eternal cause of all causes (The Most Confidential Knowledge, Text 18, Chapter 9)
