In the Nṛsiṁha Purāṇa there is a statement about King Ikṣvāku which illustrates this state of ecstatic love. Because of his great affection for Kṛṣṇa, King Ikṣvāku became greatly attached to the black cloud, the black deer, the deer's black eyes and the lotus flower, which is always compared to the eyes of the Lord. In the Tenth Canto, Thirty-eighth Chapter, verse 10, of the Bhāgavatam, Akrūra thinks, "Since the Lord has now appeared to diminish the great burden of the world and is now visible to everyone's eyes in His personal transcendental body, when we see Him before us, is that not the ultimate perfection of our eyes?" In other words, Akrūra realized that the perfection of the eyes is fulfilled when one is able to see Lord Kṛṣṇa. Therefore, when Lord Kṛṣṇa was visible on the earth by direct appearance, everyone who saw Him surely attained perfection of sight.
In the Kṛṣṇa-karṇāmṛta, written by Bilvamaṅgala Ṭhākura, there is this expression of eagerness in ecstatic love: "How miserable it is, my dear Kṛṣṇa, O friend of the hopeless! O merciful Lord, how can I pass these thankless days without seeing You?" A similar sentiment was expressed by Uddhava when he wrote a letter to Kṛṣṇa and said, "My dear Supreme King of Vraja, You are the vision of nectar for the eyes, and without seeing Your lotus feet and the effulgence of Your body, my mind is always morose. I cannot perceive any peace under any circumstance. Besides that, I am feeling every moment's separation to be like the duration of many, many long years."
In the Kṛṣṇa-karṇāmṛta it is also said, "My dear Lord, You are the ocean of mercy. With my arms placed upon my head, I am bowing down before You with all humility and sincerity. I am praying unto You, my Lord. Would You be pleased just to sprinkle a little of the water of Your glance upon me? That will be a great satisfaction."
A devotee of Lord Kṛṣṇa said, "When even Śaśiśekhara (Lord Śiva) is unable to see You, what chance is there for me, who am lower than an ordinary worm? I have only committed misdeeds. I know that I am not at all fit to offer my prayers to You, but because You are known as Dīnabandhu, the friend of the fallen, I humbly pray that You will kindly purify me by the beams of Your transcendental glance. If I become thoroughly bathed by Your merciful glance, then I may be saved. Therefore, my Lord, I am requesting You to please bestow upon me Your merciful glance.
