Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 6
Sanskrit:
यदि दूरं गत: कृष्णो वनशोभेक्षणाय तम् ।अहं पूर्वमहं पूर्वमिति संस्पृश्य रेमिरे ॥ ६ ॥
ITRANS:
yadi dūraṁ gataḥ kṛṣṇovana-śobhekṣaṇāya tamahaṁ pūrvam ahaṁ pūrvamiti saṁspṛśya remire
Translation:
Sometimes Kṛṣṇa would go to a somewhat distant place to see the beauty of the forest. Then all the other boys would run to accompany Him, each one saying, “I shall be the first to run and touch Kṛṣṇa! I shall touch Kṛṣṇa first!” In this way they enjoyed life by repeatedly touching Kṛṣṇa.
