The greatest lesson that can be drawn from this friendship is that it went far beyond the ordinary. The friendship has taken lessons forward into an era where it is most pertinent.

Origins 

These two friends were blood relatives, in fact, between Krishna's father Vasudeva and Arjuna's mother Kunti there existed a bond of brotherhood and sisterhood, thus making them cousins. This was later liberated from the limitations of family. The major meeting took place as narrated in the Adi Parva of the Mahabharata, when Krishna comes to attend the swayamvara of Draupadi in which Arjuna offered his hand.   

The greatest on knot here the Vana Parva (Book 3) of the Mahabharata describes the Krishna-Pandava relationship during their facing the hardships of forest exile, where vengeance was in fact solar-sentiment. Here we would begin to see the love of glorified humanity establishing the foundation of mutual respect that enveloped both beings during the entire epic.

This friendship evolved all the way into the brighter days during the Kurukshetra War, as witnessed in the Bhagavad Gita (chapters 25-42 of the Bhishma Parva in the Mahabharata). At this time, Arjuna was placed with an equally heavy moral dilemma, for he would not wish to ever raise his arms against his own near kinsmen. Thus it was not a mere friend, but rather one whose divineness now stood as the guide for Arjuna.  

 In Bhagavad Gita 2.10, Krishna spoke to the sorrowful Arjuna:

"tam uvāca hṛṣīkeśaḥ prahasann iva bhārata senayor ubhayor madhye viṣīdantam idam vacaḥ"

  This shifted the pivot of their entire relationship. Krishna showed himself to be not merely a friend but God, giving ultimately in Chapter 11 of the Gita the revelation of his Vishwarupa (Universal Form). However, while showing his cosmic manifestation, Krishna still retained the friendly intimacy with Arjuna, calling him "Kaunteya" (son of Kunti) and "Partha" (son of Pritha)-term of endearment.

 Lessons for Our Time

 Their friendship teaches a great deal in the modern-day morale: 

1. A Friendship Founded in Truth and Dharma 

Whenever it was conventionally hard for Krishna to instruct Arjuna in dharma, he would never hesitate. This was stated by Krishna in Bhagavad Gita 18.63:

  "iti te jñānam ākhyātaṁ guhyād guhyataraṁ mayā vimṛśyaitad aśeṣeṇa yathecchasi tathā kuru"

 "Thus I have explained to you knowledge more confidential than the confidential. Deliberate on this fully, and then do what you wish to do".

 Moral for the present: True friendship does not withdraw itself from the hard truths; it employs it in the spirit of compassion. 

 2. Unconditional Support Through Crisis

 Krishna remained steadfast during Arjuna's darkest moment of doubt and despair. In Bhagavad Gita 18.66 Krishna offers the ultimate reassurance:

"sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi mā śucaḥ"

"Abandon all varieties of dharma and just surrender unto Me. I shall deliver you from all sinful reactions. Do not fear."

Moral for the present: In times of crisis, friendship means providing unwavering support without judgment. 

 3. Balance of Equality and Honor

With respect to their eternal equality in personal status, Krishna performed these functions amidst all the inner workings of divinity with Arjuna. Krishna was the charioteer to Arjuna (in Drona Parva); yet Arjuna acknowledged Krishna's divinity. This duality, as an intimate friend and divine guide, provides a template wherein close relationships should balance intimacy with respect.

Moral: When healthily maintained, friendships provide an equal weight to both aspects described: intimacy and mutual respect.

4. Friendship as a Spiritual Partnership

 The Sanskrit expression "sakhya bhava" denotes this relationship as Krishna-Arjuna: friendship as a spiritual path. In the Udyoga Parva, Krishna says to Duryodhana: "Know that Arjuna is my other self." 

Moral today: Deep friendships can become vehicles for mutual spiritual growth and self-discovery.

 Exploring Hinduism

The Krishna-Arjuna friendship embodies the Hindu understanding that relationships are not merely social constructs but sacred bonds, capable of transformation. Their exegesis speaks that the highest form of friendship lifts both participants to dharma and spiritual awakening.

The Mahabharata opens this relationship up as a workable model for human-divine relationship, wherein God is not distant but the closest friend (suhṛdaṃ sarva-bhūtānāṃ, "friend of all beings," Gita 5.29).

For the devotees of Hindu tradition, contemplating upon this divine friendship offers an entrance to the understanding of how human relationships can become pathways to the divine and how the spiritual journey is not a solitary act but one amidst companionship from both the human side and the divine assistance.
