Dhṛtarāṣṭra said: O Sañjaya, after my sons and the sons of Pāṇḍu assembled in the place of pilgrimage at Kurukṣetra, desiring to fight, what did they do?
(BHAGAVAD-GITA-------1:1-------TRANSLATION).

The topics discussed by Dhṛtarāṣṭra and Sañjaya, as described in the Mahābhārata, form the basic principle for this great philosophy. It is understood that this philosophy evolved on the Battlefield of Kurukṣetra, which is a sacred place of pilgrimage from the immemorial time of the Vedic age. It was spoken by the Lord when He was present personally on this planet for the guidance of mankind.
(BHAGAVAD-GITA-------1:1------PURPORT).

The word dharma-kṣetra (a place where religious rituals are performed) is significant because, on the Battlefield of Kurukṣetra, the Supreme Personality of Godhead was present on the side of Arjuna. Dhṛtarāṣṭra, the father of the Kurus, was highly doubtful about the possibility of his sons' ultimate victory. In his doubt, he inquired from his secretary Sañjaya, "What did they do?" He was confident that both his sons and the sons of his younger brother Pāṇḍu were assembled in that Field of Kurukṣetra for a determined engagement of the war. Still, his inquiry is significant. He did not want a compromise between the cousins and brothers, and he wanted to be sure of the fate of his sons on the battlefield. Because the battle was arranged to be fought at Kurukṣetra, which is mentioned elsewhere in the Vedas as a place of worship—even for the denizens of heaven—Dhṛtarāṣṭra became very fearful about the influence of the holy place on the outcome of the battle. He knew very well that this would influence Arjuna and the sons of Pāṇḍu favorably, because by nature they were all virtuous. Sañjaya was a student of Vyāsa, and therefore, by the mercy of Vyāsa, Sañjaya was able to envision the Battlefield of Kurukṣetra even while he was in the room of Dhṛtarāṣṭra. And so, Dhṛtarāṣṭra asked him about the situation on the battlefield.
(BHAGAVAD-GITA-------1:1------PURPORT).

Sañjaya said: O King, after looking over the army arranged in military formation by the sons of Pāṇḍu, King Duryodhana went to his teacher and spoke the following words.
(BHAGAVAD-GITA-------1:2-------TRANSLATION).

Dhṛtarāṣṭra was blind from birth. Unfortunately, he was also bereft of spiritual vision. He knew very well that his sons were equally blind in the matter of religion, and he was sure that they could never reach an understanding with the Pāṇḍavas, who were all pious since birth. Still he was doubtful about the influence of the place of pilgrimage, and Sañjayacould understand his motive in asking about the situation on the battlefield. Sañjaya wanted, therefore, to encourage the despondent king and thus assured him that his sons were not going to make any sort of compromise under the influence of the holy place. Sañjaya therefore informed the king that his son, Duryodhana, after seeing the military force of the Pāṇḍavas, at once went to the commander in chief, Droṇācārya, to inform him of the real position. Although Duryodhana is mentioned as the king, he still had to go to the commander on account of the seriousness of the situation. He was therefore quite fit to be a politician. But Duryodhana's diplomatic veneer could not disguise the fear he felt when he saw the military arrangement of the Pāṇḍavas.
(BHAGAVAD-GITA-------1:2------PURPORT).

Sañjaya informed King Dhṛtarāṣṭra very tactfully that his unwise policy of deceiving the sons of Pāṇḍu and endeavoring to enthrone his own sons on the seat of the kingdom was not very laudable. The signs already clearly indicated that the whole Kuru dynasty would be killed in that great battle. Beginning with the grandsire, Bhīṣma, down to the grandsons like Abhimanyu and others—including kings from many states of the world—all were present there, and all were doomed. The whole catastrophe was due to King Dhṛtarāṣṭra, because he encouraged the policy followed by his sons.
(BHAGAVAD-GITA-------1:16:18------PURPORT).

Dhṛtarāṣṭra must have been very glad to understand that Arjuna was not going to fight and was instead leaving the battlefield for the begging profession. But Sañjayadisappointed him again in relating that Arjuna was competent to kill his enemies (parantapaḥ). Although Arjuna was, for the time being, overwhelmed with false grief due to family affection, he surrendered unto Kṛṣṇa, the supreme spiritual master, as a disciple. This indicated that he would soon be free from the false lamentation resulting from family affection and would be enlightened with perfect knowledge of self-realization, or Kṛṣṇa consciousness, and would then surely fight. Thus Dhṛtarāṣṭra's joy would be frustrated, since Arjuna would be enlightened by Kṛṣṇa and would fight to the end.
(BHAGAVAD-GITA-------2:9------PURPORT).

What Arjuna saw was indescribable, yet Sañjaya is trying to give a mental picture of that great revelation to Dhṛtarāṣṭra. Neither Sañjaya nor Dhṛtarāṣṭra was present, but Sañjaya, by the grace of Vyāsa, could see whatever happened. Thus he now compares the situation, as far as it can be understood, to an imaginable phenomenon (i.e., thousands of suns).
(BHAGAVAD-GITA-------11:12------PURPORT).

In the beginning of Bhagavad-gītā, Dhṛtarāṣṭra inquired from his secretary Sañjaya, "What happened on the Battlefield of Kurukṣetra?" The entire study was related to the heart of Sañjaya by the grace of his spiritual master, Vyāsa. He thus explained the theme of the battlefield. The conversation was wonderful because such an important conversation between two great souls had never taken place before and would not take place again. It was wonderful because the Supreme Personality of Godhead was speaking about Himself and His energies to the living entity, Arjuna, a great devotee of the Lord. If we follow in the footsteps of Arjuna to understand Kṛṣṇa, then our life will be happy and successful. Sañjaya realized this, and as he began to understand it, he related the conversation to Dhṛtarāṣṭra. Now it is concluded that wherever there is Kṛṣṇa and Arjuna, there is victory.
(BHAGAVAD-GITA-------18:74------PURPORT).

Vyāsa was the spiritual master of Sañjaya, and Sañjaya admits that it was by Vyāsa's mercy that he could understand the Supreme Personality of Godhead. This means that one has to understand Kṛṣṇa not directly but through the medium of the spiritual master. The spiritual master is the transparent medium, although it is true that the experience is still direct. This is the mystery of the disciplic succession. When the spiritual master is bona fide, then one can hear Bhagavad-gītā directly, as Arjuna heard it. There are many mystics and yogīs all over the world, but Kṛṣṇa is the master of all yoga systems. Kṛṣṇa's instruction is explicitly stated in Bhagavad-gītā-surrender unto Kṛṣṇa. One who does so is the topmost yogī. This is confirmed in the last verse of the Sixth Chapter. Yoginām api sarveṣām.
Nārada is the direct disciple of Kṛṣṇa and the spiritual master of Vyāsa. Therefore Vyāsa is as bona fide as Arjuna because he comes in the disciplic succession, and Sañjaya is the direct disciple of Vyāsa. Therefore by the grace of Vyāsa, Sañjaya's senses were purified, and he could see and hear Kṛṣṇa directly. One who directly hears Kṛṣṇa can understand this confidential knowledge. If one does not come to the disciplic succession, he cannot hear Kṛṣṇa; therefore his knowledge is always imperfect, at least as far as understanding Bhagavad-gītā is concerned.

(BHAGAVAD-GITA-------18:75------PURPORT).

In Bhagavad-gītā, all the yoga systems—karma-yoga, jñāna-yoga and bhakti-yoga—are explained. Kṛṣṇa is the master of all such mysticism. It is to be understood, however, that as Arjuna was fortunate enough to understand Kṛṣṇa directly, so, by the grace of Vyāsa, Sañjaya was also able to hear Kṛṣṇa directly. Actually there is no difference between hearing directly from Kṛṣṇa and hearing directly from Kṛṣṇa via a bona fide spiritual master like Vyāsa. The spiritual master is the representative of Vyāsadeva also. Therefore, according to the Vedic system, on the birthday of the spiritual master the disciples conduct the ceremony called Vyāsa-pūjā.

(BHAGAVAD-GITA-------18:75------PURPORT).

It appears that Sañjaya also, by the grace of Vyāsa, could see the universal form Kṛṣṇa exhibited to Arjuna. It is, of course, said that Lord Kṛṣṇa had never exhibited such a form before. It was exhibited to Arjuna only, yet some great devotees could also see the universal form of Kṛṣṇa when it was shown to Arjuna, and Vyāsa was one of them. He is one of the great devotees of the Lord, and he is considered to be a powerful incarnation of Kṛṣṇa. Vyāsa disclosed this to his disciple Sañjaya, who remembered that wonderful form of Kṛṣṇa exhibited to Arjuna and enjoyed it repeatedly.

(BHAGAVAD-GITA-------18:77------PURPORT).

The Bhagavad-gītā began with an inquiry of Dhṛtarāṣṭra's. He was hopeful of the victory of his sons, assisted by great warriors like Bhīṣma, Droṇa and Karṇa. He was hopeful that the victory would be on his side. But after describing the scene on the battlefield, Sañjaya told the King, "You are thinking of victory, but my opinion is that where Kṛṣṇa and Arjuna are present, there will be all good fortune." He directly confirmed that Dhṛtarāṣṭra could not expect victory for his side. Victory was certain for the side of Arjuna because Kṛṣṇa was there. Kṛṣṇa's acceptance of the post of charioteer for Arjuna was an exhibition of another opulence. Kṛṣṇa is full of all opulences, and renunciation is one of them. There are many instances of such renunciation, for Kṛṣṇa is also the master of renunciation.

The fight was actually between Duryodhana and Yudhiṣṭhira. Arjuna was fighting on behalf of his elder brother, Yudhiṣṭhira. Because Kṛṣṇa and Arjuna were on the side of Yudhiṣṭhira, Yudhiṣṭhira's victory was certain. The battle was to decide who would rule the world, and Sañjaya predicted that the power would be transferred to Yudhiṣṭhira. It is also predicted here that Yudhiṣṭhira, after gaining victory in this battle, would flourish more and more because not only was he righteous and pious but he was also a strict moralist. He never spoke a lie during his life.

(BHAGAVAD-GITA-------18:78------PURPORT).

Mahārāja Parīkṣit associated with the Lord even from the womb of his mother up to the last day of his valuable life, and thus he acquired all the essential good qualities of the Lord in all perfection.
Rantideva: An ancient king prior to the Mahābhārata period, referred to by Nārada Muni while instructing Sañjaya, as mentioned in Mahābhārata (Droṇa-parva 67). He was a great king, liberal for hospitality and distribution of foodstuff. Even Lord Śrī Kṛṣṇa praised his acts of charity and hospitality. He was blessed by the great Vasiṣṭha Muni for supplying him cold water, and thus he achieved the heavenly planet. He used to supply fruits, roots and leaves to the ṛṣis, and thus he was blessed by them with fulfillment of his desires. Although a kṣatriya by birth, he never ate flesh in his life. He was especially hospitable to Vasiṣṭha Muni, and by his blessings only he attained the higher planetary residence. He is one of those pious kings whose names are remembered in the morning and evening.

(SRIMAD BHAGAVATAM------1:12:24-------PURPORT).

Sañjaya was the personal assistant of Mahārāja Dhṛtarāṣṭra for a very long time, and thus he had the opportunity to study the life of Dhṛtarāṣṭra. And when he saw at last that Dhṛtarāṣṭra had left home without his knowledge, his sorrows had no bound. He was fully compassionate toward Dhṛtarāṣṭra because in the game of the Battle of Kurukṣetra, King Dhṛtarāṣṭra had lost everything, men and money, and at last the King and the Queen had to leave home in utter frustration. He studied the situation in his own way because he did not know that the inner vision of Dhṛtarāṣṭra has been awakened by Vidura and that therefore he had left home in enthusiastic cheerfulness for a better life after departure from the dark well of home. Unless one is convinced of a better life after renunciation of the present life, one cannot stick to the renounced order of life simply by artificial dress or staying out of the home.

(SRIMAD BHAGAVATAM------1:13:35-------PURPORT).

That great souls cheat others may be astonishing to know, but it is a fact that great souls cheat others for a great cause. It is said that Lord Kṛṣṇa also advised Yudhiṣṭhira to tell a lie before Droṇācārya, and it was also for a great cause. The Lord wanted it, and therefore it was a great cause. Satisfaction of the Lord is the criterion of one who is bona fide, and the highest perfection of life is to satisfy the Lord by one's occupational duty. That is the verdict of Gītā and Bhāgavatam.* Dhṛtarāṣṭra and Vidura, followed by Gāndhārī, did not disclose their determination to Sañjaya, although he was constantly with Dhṛtarāṣṭra as his personal assistant. Sañjaya never thought that Dhṛtarāṣṭra could perform any act without consulting him. But Dhṛtarāṣṭra's going away from home was so confidential that it could not be disclosed even to Sañjaya. Sanātana Gosvāmī also cheated the keeper of the prison house while going away to see Śrī Caitanya Mahāprabhu, and similarly Raghunātha dāsa Gosvāmī also cheated his priest and left home for good to satisfy the Lord. To satisfy the Lord, anything is good, for it is in relation with the Absolute Truth. We also had the same opportunity to cheat the family members and leave home to engage in the service of Śrīmad-Bhāgavatam. Such cheating was necessary for a great cause, and there is no loss for any party in such transcendental fraud.
