All our depression, worry patterns are nothing but root pattern of a deep fear of life, a deep self-doubt, fear of expansion and fear of losing something. You need to stand up and complete with your root thought patterns to be rid of them. Please understand, even your ignorance is nothing but your fear of expansion. Many times, you continue to pretend to be in ignorance, because of your fear of failure.

You always believe that you are suffocated by your smallness. NO! You are suffocated by your bigness!

There are many levels of fear: fear of losing our wealth and status, fear of losing a limb or our health, fear of losing our near and dear ones and fear of the unknown or death. That is why Kṛṣṇa says that Arjuna is not behaving as an ārya, a word that can be interpreted as a nobleman; an integrated human, not a particular race or caste. Vedic literatures say that an ārya is one who is evolved, cultured, integrated and authentic, a prince amongst men.

Arjuna is confronted with all the four fears: fear that he may lose whatever he possesses, that he may be maimed in the war, that he may lose his near and dear ones, and fourth, that he may lose his very life. These fears have in turn led to his powerlessness of heart. Understand, all your fears, all your anxieties, all your patterns are directed only in one line – fear of your possibilities!

Listen!

Your bigness frightens you. You always believe that you are suffocated by your smallness. NO! You are suffocated by your bigness! Whenever bigness is demanded of you, whenever you feel you are being ‘forced’ to expand, you shrink even further into your comfort zone. Arjuna’s tiredness, his weakness, his powerlessness all these are nothing but the resistance he has to seeing his own bigness!

The more you engage with life, the greater the expansion that will be demanded of you.

That is why, when someone tells you that you are weak, poor and a sinner, it is so easy to accept it. But if someone tells you that you are Divine, you are powerful, you are complete, your whole identity starts trembling with fear! Arjuna trembles and collapses totally fearing his bigness, shrinking into his weak-heartedness! But life always demands your expansion, because expansion is the natural law of life. Here, Kṛṣṇa, the source of life, demands Arjuna to stand up and expand into his powerfulness, and give up his degrading powerlessness unbefitting an ārya prince, who is also famous as Parantapa, conqueror of enemies. But Arjuna is carrying such a deep fear of life, especially fear of life in the form of other people—because people are the most living expression of Life! The whole Kaurava army and his dear ones are the people who now represent his deepest fears of life.

Listen! The more you engage with life, the greater the expansion that will be demanded of you. Whenever you are feeling weak, tired, and powerless, the first thing you should do is this: immediately take on ten responsibilities and commit to fulfill them within an impossibly short time! Shake your inner space so powerfully with that commitment that there will be no way for weakness and tiredness to grow inside you.
Kṛṣṇa directly addresses this weakness, powerlessness in Arjuna and the fear of life in the form of his kinsmen with the śāstra, the explanation of wisdom that is directed to the head, the intellect. He shakes Arjuna’s inner space demanding of him to take up the responsibility to stand up and commit to powerfully uproot all his impossibilities, and fight—tyaktvottiṣṭha parantapa!

Later on in the Gītā, in the eleventh chapter, after beholding Kṛṣṇa’s cosmic vision, Arjuna realizes who Kṛṣṇa truly is; that He is beyond everything and beyond his imagination, his comprehension. He is not surprised any longer that all the deities worship Him and surrender to Him. Kṛṣṇa then repeats the same words that He says now, after which the Gītā ends and Arjuna engages in the war.

These same words uttered by Kṛṣṇa later on, when Arjuna is in the state of stotra, a state of pure devotion and faith, become the sūtra, the technique of enlightenment for Arjuna.

Listen! When you are in devotion, you will just live life. You will not have any fear. Fear is always out of powerlessness. When you are in love, you will not know anything called fear or worry. That stage is yet to happen. Since Arjuna is not yet in the devotional state now, these words are only plain wisdom.

Kṛṣṇa is not a philosopher; He is a personification of enlightenment, of infinite powerfulness. All philosophy is an attempt to convince the other to do what the philosopher wants of him. Philosophers are the most dangerous people who invent logical reasons that encage, enslave or engage you to follow their words. Here, Kṛṣṇa straightaway enriches by giving the conclusion directly to Arjuna. However, as Arjuna is not in the complete space to receive it because he is not mature enough to assimilate it, Kṛṣṇa needs to give Arjuna the experience.

Please listen! When you started having a root pattern, when you first had powerlessness, after that you never grow. Arjuna’s age is sealed mentally. Physically he may be a grown-up, as a warrior among warriors, but mentally his age is sealed. Only when Kṛṣṇa gives the experience of His own space of completion to Arjuna, he expands; he becomes powerful, he matures into a ripened enlightened soul.

There is a beautiful story in the Upaniṣads:

A disciple goes to the Master and asks, ‘O master! Teach me atmajñāna, knowledge of inner Self.’

The Master says, ‘Thou art that! Tattvamasi. You are God.’

The disciple, unable to believe this, thinks to himself, ‘How can I be God? I am still afraid of my wife. I have all these problems and a thousand questions!’

Only when the Master proves to him that the Master himself is God, the disciple trusts the Master’s words.
The Master needs to first prove that he is God in order to make you understand that you are God. Here Kṛṣṇa does the same thing by repeating that He is all of this. Kṛṣṇa later explains His glory and that all the deities, Vedas, the scriptural wisdom, are worshipping at His feet; the whole world is in Him. He makes these incredible statements that would appear egoistic to a normal person. And yet Kṛṣṇa says all this, even at the risk of being misunderstood. He repeats that He is God to make you realize that you are God.
With authority He states, ‘I am God’ to make you realize that you are God.

Continuously human beings resist expansion. Incarnations happen on the planet to remind human beings about their possibilities, to expand human consciousness. That is why again and again they are doubted. Arjuna is Nara, human being who resists his expansion, and Śrī Kṛṣṇa is Nārāyaṇa, Divine Incarnate who reminds him of his highest possibility of expansion—that he is God, that Nara is the reflection of Nārāyaṇa, who is mirroring the infinite inner space of God!

You would not believe the words of ordinary people. You need to listen to the words from a source of authority that has the right to say them. Here Kṛṣṇa says the same words that He repeats throughout the entire Gītā. But as of now Arjuna is not able to take it all in. It is too much for him to grasp in his present condition.

Once Kṛṣṇa proves His divinity, Arjuna believes His words and is ready to follow them. Similarly, when masters prove their divinity and express great powers or miracles of their energies, they do not do so for their ego satisfaction. They do them to prove that they are God, so that you believe their words and experience that you are God.

Understand: when I am expressing the aṣṭa mahāsiddhis, extraordinary eight yogic powers, it is not to show that I am extraordinary; it is just to show that it is possible for you! Nothing more is required than carrying the space of possibility, with the understanding—‘When Swamiji can do it, I can do it!’ That’s all!

It is the authority with which Kṛṣṇa is seen transmitting the Gītā that makes it a scripture. ‘I am the Divine,’ says Kṛṣṇa. ‘If you believe in Me, you too shall realize your inner divinity.’ It is this profound and yet simple message that has resounded so deeply in the hearts, minds and beings of generations of Hindus, in turn establishing the scriptural sanctity of the Gītā.
