What are the rules to read bhagavad geeta?

Krsna calls the Bhagavad Gita Raja Vidya and Raja Guhyam, the King of all knowledge and the most confidential of all secrets.

But why? Why is Bhagavad Gita considered to be the topmost knowledge and why is it labelled as the most confidential secret? Since Krsna spoke it to Arjuna and Vedavyas presented it to the world, millions and billions of people have had access to it - it is basically open for everyone to read, understand and apply, so why is it still the most confidential knowledge?

Bhagavad Gita is like an open secret, it’s in front of you and yet you shall never truly know its complete import.

Why?

Firstly, because it deals with subject matter beyond the perception of our senses, beyond the mind, intelligence and ego. It’s like Einstein once famously stated - ‘We can’t solve a problem by the same thinking with which we created it’, so how then do you expect to understand the Soul which is above the platform of your senses, mind, intelligence and ego?

Secondly, even if you were to attempt understanding the Gita by yourself and speculate for millions and trillions of years and lifetimes, you’d still be unable to see the simple truth staring right back at you, the truth about the Supreme Lord and everything within.

Why? Parampara.

You can never understand the Supreme Absolute Truth without the mercy of great great spiritual masters coming from an unbroken chain of disciplic succession starting from the Lord Himself. It’s there, very much there. Only, we should be sincere enough to seek it, and like they say ‘the universe will conspire to make it happen’.

Nevertheless, that is your only real rule and qualification needed - read the Bhagavad Gita under guidance from someone who’s linked to an authorised Parampara.

evaṁ paramparā-prāptam

imaṁ rājarṣayo viduḥ

This supreme science was thus received through the chain of disciplic succession, and the saintly kings understood it in that way.

(Bhagavad Gita 4.2)
