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!"
Similar feelings were expressed by the gopīs when they were going to the bank of the Yamunā and saw Kṛṣṇa's footprints in the dust. When Kṛṣṇa walked on the ground of Vṛndāvana, the marks of His sole (flag, thunderbolt, fish, a rod for controlling elephants and lotus flower) would be imprinted upon the dust of the land. The gopīs became overwhelmed simply at seeing those marks on the ground.
Kṛṣṇa's Places of Pastimes
One devotee has exclaimed, "Oh, I have not as yet visited the wonderful places where the pastimes of the Lord were performed. But simply by hearing the name of Mathurā I have become overwhelmed with joy!"
Kṛṣṇa's Favorite Plant: Tulasī
Lord Kṛṣṇa is very fond of tulasī leaves and buds. Because tulasī buds are usually offered up to the lotus feet of Kṛṣṇa, a devotee once prayed to the tulasī buds to give him some information about the lotus feet of the Lord. The devotee expected that the tulasī buds would know something about the glories of Lord Śrī Kṛṣṇa's lotus feet.
Kṛṣṇa's Devotees
One may sometimes become overwhelmed with joy by seeing a devotee of the Lord. When Dhruva Mahārāj saw two associates of Nārāyaṇa approaching him, he immediately stood up out of sincere respect and devotion and remained before them with folded hands; but because of his ecstatic love he could hardly offer them a proper reception.
