Essence of Seven Mukhi Rudraksha:

As per our scriptures, The 7 Mukhi Rudraksha is of Anang form. Even a poor person becomes Ishwar (Full of Possessions) by wearing it. The 7 Mukhi Rudraksha is blessed by the Saptamatrikas and provides the blessings of Goddess Lakshmi. The 7 Sages known as Saptarishis, Sun, Mahasen, Anang and Ananta, the snake also bless this bead.

The word “Ananta” (infinite) actually gives an insight into the several powers the wearer of this bead can access. In the scriptures Lord Vishnu has told that of all the snakes he is Ananta. Lord Vishnu is often depicted with Sthira (stable) Lakshmi on Ananta. Thus this bead carries the power of Goddess Lakshmi in her most stable form. The blessing of Goddess Lakshmi brings in wealth, fame, progress and removes bad luck. This power is experienced by the wearer of this bead as per texts.
