Bhagavad Gita - II 55

A man of steady intellect

Sri Bhagavan Uvacha
Prajahathi Yada Kaman Sarvan Partha Manogathan|
Athmanyevathmana Tushtaha Sthithapragnyasthadochyate||

Dear Partha, when someone abandons all the desires of the mind and is satisfied in just being with the atman, that person is called a Sthitha Pragnya. Desires in different directions disturb the mind and make it unsteady. A Sthitha Pragnya is one whose mind is totally contained without going in the different directions of individual desires. Such a person has a steady mind called Sthitha Pragnya. - Swahilya Shambhavi.

Arjuna's question

Sthitha Pragnyasya Ka Bhasha Samadhistasya Keshava|
Sthitha Dheehi Kim Prabhashetha Kimaseetha Vrajetha Kim||

India prides itself today on many of its ancient discoveries - the concept of zero, the science of flying airplanes - Vaimanika Shastram etc. But the greatest discovery it offers to the world is this knowledge of the self, through the words of the Bhagavad Gita and other books.
Arjuna asks Sri Krishna, "What is the description of a person of steady wisdom or an illumined mind? What is the nature of his steady intellect? A man with rooted intellect - how does he speak? How does he sit and walk?
Arjuna here asks Krishna to give the gross details of a man of steady wisdom - such as appearance, body language, speech and thought patterns. - Swahilya Shambhavi.

The Bhagavad Gita - II - 53

Rooting the head deep

Shrutivipratipanna te yada sthasyathi Nishchala|
Samadhavachala Buddhihi Tada Yogamavapsyasi||

When the intellect that is being fed constantly by the mind with conflicting thoughts and images, stands without movement rooted deeply in consciousness, at that time you achieve the state of yoga, says Sri Krishna.
In any crisis, the sense organs feed the mind with numerous thoughts - Oh! this is happening now. There is just Rs. 70 in my bank account. I have so many bills to pay and so many things to buy. How am I going to manage that?
All that time, if the intellect takes the decision to root itself in consciousness, then the state of yoga or connectivity with the universal consciousness is achieved.
- Swahilya Shambhavi.

Transcend the delusory mind

Yada Te Moha Kalilam Buddhivyati tarishyati|
Tada Gantasi Nirvedam Shrotavyasya Shrutasyacha||

Whe your intellect transcends the mixture of illusion, then you remain untouched by the experiences of all that you have heard and are yet to hear about. When the intellect is rooted in purity, transcending the mind, then nothing seen, heard or experienced affects its stability. - Swahilya Shambhavi.
