Kṛṣṇa's Buffalo Horn
Kṛṣṇa used a buffalo horn as a bugling instrument. This instrument was always highly polished and circled with gold bands, and on the middle there was a hole. Regarding these instruments, there is a metaphorical statement about a gopī named Tārāvalī. It is said that Tārāvalī became bitten by the most venomous snake of Kṛṣṇa's flute. Then, in order to neutralize the poisonous effect, she drank the milk produced by the buffalo horn in the hand of Kṛṣṇa. But instead of decreasing the poisonous effect, it increased it a thousand times. The gopī was thus put into the most miserable poisoned condition. The Attraction of Kṛṣṇa's Leg Bells
A certain gopī once stated to her friend, "My dear friend, when I heard the sound of the leg bell of Śrī Kṛṣṇa, I immediately started to go out of the house to see Him. But most regrettably, my superiors were present just before me at that time, and I could not go out."
Kṛṣṇa's Conchshell
Kṛṣṇa's conchshell is known as Pāñcajanya. This Pāñcajanya conch is also mentioned in the Bhagavad-gītā. Kṛṣṇa sounded it before the Battle of Kurukṣetra. It is said that when Lord Kṛṣṇa blows on His transcendental conchshell, the wives of the demons become subject to abortions, and the wives of the demigods become blest with all auspiciousness. In this way, the sound of Kṛṣṇa's conchshell used to vibrate and circulate all over the world.
Kṛṣṇa's Footprints
It is stated in the Śrīmad-Bhāgavatam that when Akrūra, who drove Kṛṣṇa from Vṛndāvana to Mathurā, saw the footprints of Kṛṣṇa on the land of Vṛndāvana, his ecstatic love for Kṛṣṇa increased so much that the hairs on his body stood up. His eyes became overflooded with tears, and in such ecstasy he jumped out of the chariot and fell down on the ground and began to chant, "How wonderful this is! How wonderful this is!"
