Ṣaḍ-bhuja (Six-armed Lord Gaurasundara)

Information – Sārvabhauma Bhaṭṭācārya was so fortunate as to see the six-armed form of Lord Caitanya known as Ṣaḍbhuja in Jagannath Puri. A Sadbhuja deity commemorating this pastime is installed in this temple.
Additionally, a Ṣaḍbhuja deity is also installed at Chaitanya Math in Antardvipa.

He started a school at Jagannātha Purī for the study of Vedānta philosophy, of which he was a great scholar. When Sārvabhauma Bhaṭṭācārya met Śrī Caitanya Mahāprabhu, he advised the Lord to learn Vedānta philosophy from him, but later he became a student of Lord Caitanya Mahāprabhu to understand the real meaning of Vedānta. Sārvabhauma Bhaṭṭācārya was so fortunate as to see the six-armed form of Lord Caitanya known as Ṣaḍbhuja. A Ṣaḍbhuja Deity is still situated at one end of the Jagannātha temple. Daily saṅkīrtana performances take place in this part of the temple.
(CC Adi 10.130 purport)

The form of Ṣaḍ-bhuja, the six-armed Lord Gaurasundara, is a representation of three incarnations. The form of Śrī Rāmacandra is symbolized by a bow in one hand and an arrow in another, the form of Lord Śrī Kṛṣṇa is symbolized by a stick and a flute like those generally held by a cowherd boy, and Lord Caitanya Mahāprabhu is symbolized by a sannyāsa-daṇḍa and a kamaṇḍalu, or waterpot….
(CC Ādi 17.12)

One day Lord Caitanya Mahāprabhu exhibited to Lord Nityānanda Prabhu a six-armed form bearing a conchshell, disc, club, lotus flower, bow and flute.
