Rudraksha bead 2 faces

2-faced Rudraksha - the Grace of Ardhanarishvara (the deity is an androgen, combines male and female qualities and personifies the unity of two opposites). The two-faced Rudraksha represents the unity of Shiva and Shakti, or Rudra and Parvati. Vaishnavas call it the symbol of Vishnu. Thus, the two-faced Rudraksha is revered by both Shaivites and Vaishnavites.
