Bhagavan Sri Ramana Maharshi was asked by his devotees was once asked by his pupils to simplify their study of Bhagavadgita . The disciples complained that the Bhagavadgit has 700 verses and is too long and they asked Bhagavan to choose the most important verses. Bhagavan told them that in the verse of 10.20 his teachings of eternity are summarized. But it seemed little to the devotees, so Bhagavan made a selection of 42 verses from different chapters of the Bhagavadgita and arranged them and created his new chapter that summarizes the essence of the world and various spiritual exercises that eventually lead to eternal happiness. Bhagavan translates these verses from Sanskrit into Tamil and now sings in the Sri Ramana Ashram every week on Thursday evening as part of a regular Tamil Parayana - the singing of the spiritual texts. The Sanskrit version of the selected verses is sung every Sunday in the Sanskrit parayana.
It is amazing to see how Sri Raman chose Scripture verses and how he compiled them into a beautiful and clear whole.

To him who had been thus filled with pity, whose eyes were filled with tears and showed distress, and who was sorrowing, Madhusudana uttered these words:
The Blessed Lord said
O son of Kunti, this body is referred to as the 'field'. Those who are versed in this call him who is conscious of it as the 'knower of the field'.
And, O scion of the Bharata dynasty, under-stand Me to be the 'Knower of the field' in all the fields. In My opinion, that is Knowledge which is the knowlege of the field and the knower of the field.
O Gudakesa, I am the Self residing in the hearts of all beings, and I am the beginning and the middle as also the end of (all) beings.
For death of anyone born is certain, and of the dead (re-) birth is a certainly. Therefore you ought not to grieve over an inevitable fact.
Never is this One born, and never does It die; nor is it that having come to exist, It will again cease to be. This One is birthless, eternal, undecaying, ancient; It is not killed when the body is killed.
It cannot be cut, It cannot be burnt, cannot be moistened, and surely cannot be dried up. It is eternal, omnipresent, stationary, unmoving and changeless.
But know That to be indestructible by which all this is pervaded. None can bring about the destruction of this Immutable.
Of the unreal there is no being; the real has no nonexistence. But the nature of both these, indeed, has been realized by the seers of Truth.
Being without beginning and without qualities, O son of Kunti, this immutable, supreme Self does not act. nor is It affected, although existing in the body.
Neither the sun nor the moon nor fire illumines That. That is My supreme Abode, reaching which they do not return.
He who has been mentioned as the Unmanifested, the Immutable, they call Him the supreme Goal. That is the supreme abode of Mine, reaching which they do not return.
The wise ones who are free from pride and non-discrimination, who have conquered the evil of association, who are ever devoted to spirituality, completely free from desires, free from the dualities called happiness and sorrow, reach that undecaying State.
He who, sitting like one indifferent, is not distracted by the three qualities; he who, thinking that the qualities alone act, remains firm and surely does not move;
He sees who sees the supreme Lord as existing equally in all beings, and as the Imperishable among the perishable.
But, O Arjuna, by single-minded devotion am I-in this form-able to be known and seen in reality, and also be entered into, O destroyer of foes.
O scion of the Bharata dynasty, the faith of all beings is in accordance with their minds. This person is made up of faith as the dominant factor. He is verily what his faith is.
The man who has faith, is diligent and has control over the organs, attains Knowledge. Achieving Knowledge, one soon attains supreme Peace.
To them who are ever devoted and worship Me with love, I grant that possession of wisdom by which they reach Me.
Out of compassion for them alone, I, residing in their hearts, destroy the darkness born of ignorance with the luminous lamp of Knowledge.
But in the case of those of whom that ignorance of theirs becomes destroyed by the knowledge (of the Self), their Knowledge, like the sun, reveals that supreme Reality.
They say that the organs are superior (to the gross body); the mind is superior to the organs; but the intellect is superior to the mind. However, the one who is superior to the intellect is He.
Understanding the Self thus *as superior to the intellect, and completely establishing (the Self) is spiritual absorption with the (help of) the mind, O mighty-armed one, vanquish the enemy in the form of desire, which is difficult to subdue.
O Arjuna, as a blazing fire reduces pieces of wood to ashes, similarly the fire of Knowledge reduces all actions to ashes.
The wise call him learned whose actions are all devoid of desires and their thougts, and whose actions have been burnt away by the fire of wisdom.
To the monks who have control over their internal organ, who are free from desire and anger, who have known the Self, there is absorption in Brahman either way.
One should gradually withdraw with the intellect endowed with steadiness. Making the mind fixed in the Self, one should not think of anything whatsoever.
(The yogi) should bring (this mind) under the subjugation of the Self Itself, by restraining it from all those causes whatever due to which the restless, unsteady mind wanders away.
the contemplative who has control over his organs, mind and intellect should be fully intent on Liberation and free from desire, fear and anger. He who is ever is verily free.
One who has his mind Self-absorbed through Yoga, and who has the vision of sameness every-where, see this Self existing in everything, and every-thing in his Self.
Those persons who, becoming non-different from Me and meditative, worship Me everywhere, for them, who are ever attached (to Me), I arrange for securing what they lack and preserving what they have.
Of them, the man of Knowledge, endowed with constant steadfastness and one-pointed devotion, excels. For I am very much dear to the man of Knowledge, and he too is dear to Me.
At the end of many births the man of Knowledge attains Me, (realizing) that Vasudeva is all. Such a high-souled one is very rare.
The Blessed said
O Partha, when one fully renounces all the desires that have entered the mind, and remains satisfied in the Self alone by the Self, then he is called a man of steady wisdom.
That man attains peace who, after rejecting all desires, moves about free from hankering, without the idea of ('me' and) 'mine', and devoid of pride.
He, too, owing to whom the world is not disturbed, and who is not disturbed by the world, who is free from joy, impatience, fear and anxiety, is dear to Me.
He who is the same under honour and dishonour, who is equally disposed both towards the side of the friend and of the foe, who has renounced all enterprise,-he is said to have gone beyond the qualities.
But that man who rejoices only in the Self and is satisfied with the Self, and is contented only in the Self-for him there is no duty to perform.
For him there is no concern here at all with performing action; nor any (concern) with nonperformance. Moreover, for him there is no dependence on any object to serve any purpose.
Remaining satisfied with what comes unasked for, having transcended the dualities, being free from spite, and equipoised under success and failure, he is not bound even by performing actions.
O Arjuna, the Lord resides in the region of the heart of all creatures, revolving through Maya all the creatures (as though) mounted on a machine!
Take refuge in Him alone with your whole being, O scion of the Bharata dynasty. Through His grace you will attain the supreme Peace and the eternal Abode.
