And not only that, he is intimately in touch with Kṛṣṇa as friend. Therefore Bhagavad-gītā is understood by a person who has similar qualities like Kṛṣṇa. That means he must be a devotee, he must be in relation, direct relationship with the Lord. As soon as one becomes a devotee of the Lord, he has a direct relationship also with the Lord. That is a subject matter very long, but briefly it can be stated that a devotee is in relationship with the Supreme Personality of Godhead in five ways. One may be a devotee in a passive state, one may be a devotee in active state, one may be a devotee as a friend, one may be a devotee as parent, and one may be a devotee as conjugal lover.
So Arjuna was a devotee in relationship with the Lord as a friend. The Lord can become a friend. Of course, this friendship and the conception of friendship which we have got in the mundane world, there is a gulf of difference. This is transcendental friendship which... Not that everyone will have the relationship with the Lord. Everyone has got a particular relationship with the Lord and that particular relationship is evoked by the perfection of devotional service. At the present status of our life we have not only forgotten the Supreme Lord, but also we have forgotten our eternal relationship with the Lord. Every living being, out of many, many millions and billions of living beings, each and every living being has got a particular relationship with the Lord eternally. That is called svarūpa. Svarūpa. And by the process of devotional service one can revive that svarūpa of oneself. And that stage is called svarūpa-siddhi, perfection of one's constitutional position. So Arjuna was a devotee and he was in touch with the Supreme Lord in friendship.
