jāto ’yaṁ kaṇṭaka-drumaḥ
viṣṇor nālāyito ’rbhakaḥ
Thorn trees generally grow in deserted places, not in sandalwood forests, but the seminal brāhmaṇas Ṣaṇḍa and Amarka compared the dynasty of the Daitya Hiraṇyakaśipu to a sandalwood forest and compared Prahlāda Mahārāja to a hard, strong thorn tree that could provide the handle of an axe. They compared Lord Viṣṇu to the axe itself. An axe alone cannot cut a thorn tree; it needs a handle, which may be made of the wood of a thorn tree. Thus the thorn tree of demoniac civilization can be cut to pieces by the axe of viṣṇu-bhakti, devotional service to Lord Kṛṣṇa. Some of the members of the demoniac civilization, like Prahlāda Mahārāja, may become the handle for the axe, to assist Lord Viṣṇu, and thus the entire forest of demoniac civilization can be cut to pieces.
