om ajnana-timirandasya

om ajnana-timirandasya jnananjnana salakaya
caksur unmilitam yena tasmai sri gurave namah

 

I offer my most humble obeisances to my spiritual master who has opened my eyes which were blinded by ignorance with the light of knowledge.

raja-vidya raja-guhyam pavitram idam uttamam
pratyak savagamam dharmyam susukham kartum avyayam

This knowledge is the king of all wisdom, the king of all that is confidential. It is the purest and the topmost and because it gives direct perception of the self by realization it is the perfection of all religion and everlastingly joyful to perform.

Bhagavad-Gita, chapter 9, verse 2
