10 Mukhi Rudraksha asdescribed in various Puranas :

Lord Vishnu, major god of Hinduism and Indian mythology, popularly regarded as the preserver of the universe. Some Puranic literature refers to him as the eternal,
all-pervading spirit and associates him with the primeval waters believed to have been omnipresent before the creation of the world. So regarded, Vishnu is depicted frequently in human form, sleeping on the great serpent Shesha and floating on the waters. One hand holds a lotus; a second holds a conch; a third holds a discus (which always returns by itself after being thrown); and the fourth carries a mace. The petals of the lotus are believed to symbolize the unfolding of creation; the conch is said to symbolize that from which all existence originates; and the discus and the mace reputedly were obtained by Lord

Vishnu as rewards for defeating the God Indra. Lord Vishnu is said to possess also a special sword called Nadaka and a special bow called Sarnga. His wife is Goddess Lakshmi (also known as Shri), goddess of beauty and fortune. He rides a huge creature, half bird and half man, called Gandara. His home is in a heaven called Vaikuntha (where the Ganges River is believed to flow from its source at Vishnu's feet). The god has a thousand names, the repetition of which is regarded as an act of devotion.
