In Śrīmad-Bhāgavatam (10.89.58) the Bhūmā-puruṣa (Mahā-Viṣṇu) told Kṛṣṇa and Arjuna, “My dear Kṛṣṇa and Arjuna, I have taken the brāhmaṇa's sons just to see you.” Arjuna had attempted to save some youths who had died untimely at Dvārakā, and when he failed to save them, Kṛṣṇa took him to the Bhūmā-puruṣa. When the Bhūmā-puruṣa brought forth those dead youths as living entities, He said, "Both of you appeared in order to preserve religious principles in the world and to annihilate the demons." In other words, the Bhūmā-puruṣa, being also attracted by the beauty of Kṛṣṇa, concocted this pastime just as a pretext to see Him. It is recorded in Śrīmad-Bhāgavatam (10.16.36) that after the serpent Kāliya was punished by Kṛṣṇa, one of Kāliya's wives told Kṛṣṇa, "Dear Lord, we cannot understand how this fallen serpent got the opportunity of being kicked by Your lotus feet when even the goddess of fortune underwent austerities for many years just to see You."
How Kṛṣṇa is attracted by His own beauty is described in the Lalita-mādhava (8.34). Upon seeing His own picture, Kṛṣṇa lamented, "How glorious this picture is! It is attracting Me just as it attracts Rādhārāṇī."
After giving a summary description of Kṛṣṇa's beauty, Rāmānanda Rāya began to speak of His spiritual energies, headed by Śrīmatī Rādhārāṇī. Kṛṣṇa has immense energetic expansions, of which three are predominant: the internal energy, the external energy and the marginal energy, comprising the living entities. This threefold division of energies is confirmed in the Viṣṇu Purāṇa (6.7.61), where it is said that Viṣṇu has one spiritual energy, which is manifested in three ways. When the spiritual energy is overwhelmed by ignorance, it is called the marginal energy. As far as the spiritual energy itself is concerned, it is exhibited in three forms because Kṛṣṇa is a combination of eternity, bliss and knowledge. As far as His bliss and peacefulness are concerned, His spiritual energy is manifested as the pleasure-giving potency. His eternity is a manifesting energy, and His knowledge is manifested as spiritual perfection. As confirmed in the Viṣṇu Purāṇa (1.12.69): "The pleasure potency of Kṛṣṇa gives Kṛṣṇa transcendental pleasure and bliss." Thus when Kṛṣṇa wants to enjoy pleasure, He exhibits His own spiritual potency known as āhlādinī.
In His spiritual form, Kṛṣṇa enjoys His spiritual energy, and that is the sum and substance of the Rādhā-Kṛṣṇa pastimes. These pastimes can be understood only by elevated devotees. One should not try to understand the Rādhā-Kṛṣṇa potencies and pastimes from the mundane platform. Generally people misunderstand these as being material.
When the pleasure potency is further condensed, it is called mahābhāva. Śrīmatī Rādhārāṇī, the eternal consort of Kṛṣṇa, is the personification of that mahābhāva. In this regard, in the Ujjvala-nīlamaṇi (4.3) Rūpa Gosvāmī states that there are two competitors in loving Kṛṣṇa—Rādhārāṇī and Candrāvalī. When they are compared, it appears that Rādhārāṇī is superior, for She is mahābhāva-svarūpa. The term mahābhāva-svarūpa, "the personification of mahābhāva," is applicable to Rādhārāṇī only, and no one else. Mahābhāva is full of the pleasure potency, and it is an exhibition of the highest love for Kṛṣṇa. Rādhārāṇī is therefore known throughout the world as the most beloved of Kṛṣṇa, and Her name is always associated with Kṛṣṇa as Rādhā-Kṛṣṇa.
