The Ek Mukhi Rudraksha is believed to be Lord Shiva himself. To understand the power of this Rudraksha first we must understand the aspect of Shiva.
Shlokas describe Shiva as “Niraakar, Omkara, Mula Turiyam”; Shapeless, Formless without any beginning or end. Shiva is a constant energy who is in eternal bliss. This energy has a uni-vibrational frequency that can be tapped by the Shiv Panchakshari (Namah Shivaya). Chanting this with faith is the only way to log on to this powerful uni-vibrational being.
In our scriptures there is a story. Lord Shiva was in his beautiful meditative state on the icy mount Kailash. Parvati his divine consort was pondering over her simple existence wondering why only riches, splendour and a bejewelled appearance should be associated with Goddess Lakshmi. She requested Shiva that he should grant her a rich luxurious abode that is unmatched in beauty, wealth and splendour. The compassionate Lord immediately granted her this wish and ordered Yaksharaja Kubera to build a palace called Shivnagari. This township was an architectural marvel embedded with riches. Parvati was elated and accompanied Shiva to live in this new rich abode. She adorned herself with jewellery and silken attire. When she approached Lord Shiva his eyes were closed and he was in his usual meditative state. Shiva the supreme soul was neither affected by living in the mountains nor amidst splendour and riches. His blissful form made her realise what is true happiness. She asked for forgiveness and returned to Kailash and to stay blissfully with the eternal Shiva.
Just like Lord Shiva who could command unparalleled riches in one moment and stay unaffected by it the One Mukhi Rudraksha grants such a power to its wearer as per texts. The Shiv Puran (Ch. 25, Sl. 65) clearly mentions that Goddess Laxmi never leaves the place where a One Mukhi Rudraksha is worshipped. In other words a man blissfully enjoys unlimited wealth while existing with detachment and bliss.
