Śukadeva Gosvāmī said: While traveling far and wide visiting various holy places of pilgrimage, Arjuna came to Prabhāsa. There he heard that Lord Balarāma intended to give his maternal cousin Subhadrā to Duryodhana in marriage, and that no one else approved of this plan. Arjuna wanted to marry her himself, so he disguised himself as a renunciant, complete with triple staff, and went to Dvārakā. KB 10.86.2-3 Thus Śukadeva Gosvāmī began to narrate the story as follows: Once upon a time, King Parīkṣit’s grandfather Arjuna, the great hero, was visiting several holy places of pilgrimage, and while thus traveling all over he happened to come to Prabhāsa-kṣetra. In Prabhāsa-kṣetra he heard the news that Lord Balarāma was negotiating the marriage of Subhadrā, the daughter of Arjuna’s maternal uncle, Vasudeva. Although her father, Vasudeva, and her brother Kṛṣṇa were not in agreement with Him, Balarāma was in favor of marrying Subhadrā to Duryodhana. Arjuna, however, desired to gain Subhadrā’s hand himself. As he thought of Subhadrā and her beauty, Arjuna became more and more captivated with the idea of marrying her, and with a plan in mind he dressed himself like a Vaiṣṇava sannyāsī, carrying a tridaṇḍa in his hand. The Māyāvādī sannyāsīs take one daṇḍa, or one rod, whereas the Vaiṣṇava sannyāsīs take three daṇḍas, or three rods. The three rods, or tridaṇḍa, indicate that a Vaiṣṇava sannyāsī vows to render service to the Supreme Personality of Godhead with his body, mind and words. The system of tridaṇḍa-sannyāsa has been in existence for a long time, and the Vaiṣṇava sannyāsīs are called tridaṇḍīs, or sometimes tridaṇḍi-svāmīs or tridaṇḍi-gosvāmīs.
