The two goldfish (Sanskrit: Gaur-matsya; Tibetan: ག་, Wylie: gser nya), representing the state of fearless suspension in a harmless ocean of samsara, metaphorically often refer to buddha-eyes or rigpa-sight; symbolises the auspiciousness of all sentient beings in a state of fearlessness without danger of drowning in the Samsaric Ocean of Suffering, and migrating from place to place and teaching to teaching freely and spontaneously just as fish swim freely without fear through water.
In the following quotation, the two golden fishes are linked with the Ganges and Yamuna, and nadi, prana and carp:
The two fishes originally represented the two main sacred rivers of India - the Ganges and Yamuna. These rivers are associated with the lunar and solar channels, which originate in the nostrils and carry the alternating rhythms of breath or prana. They have religious significance in Hindu, Jain and Buddhist traditions but also in Christianity (the sign of the fish, the feeding of the five thousand). In Buddhism, the fish symbolize happiness as they have complete freedom of movement in the water. They represent fertility and abundance. Often drawn in the form of carp, which are regarded in the Orient as sacred on account of their elegant beauty, size, and life-span.
