This is a statement of the queen of Vṛndāvana, Rādhā, who would relish Kṛṣṇa at every moment. Because of the strength of the expression in the verse, it is understood that she experienced Kṛṣṇa in increasingly unique ways. Thus the verse is used as an example of ever-freshness. Chaṭa means a fine tip. The word is also found in the phrase saṭācchaṭābhinna-ghaṇa (solid with a fine tip) from Śisupāla-vadha. Kakṣa means an enclosure according to Amara-kośa. The fence appears to be made of sapphires because of the rays emanating from Kṛṣṇa’s blackish body. But there is something remarkable here in Kṛṣṇa. While doing the difficult work of constructing a cow pen out of sapphires (so it appears), He simultaneously breaks the stones of self-control of the gopīs. The hint here is that it is not intentional on His part to break the gopīs’ dharma.
