Two naturally joined Rudraksha called Gauri Shankar is regarded as the form of Shiva & Parvati. It is so much full of influence that it causes the development and expansion of universe due to its being the unified and identified form of the Lord Shiva and the Goddess Uma. This form becomes the cause of expansion of the universe providing fertility. It makes the husband and wife identify each other. Therefore it is regarded the best thing for peace and comfort in the family. So, it is the most preferred gift as ancient texts mention that gifting rudraksha accrues punya (good karma).

If a man worships Gauri Shankar at his worshipping place, the pain and suffering and other earthly obstacles are destroyed and the peace and pleasure of family are increased. In Puranas the bead of Gauri Shankar is regarded the best for happy family life. A sannyasi (saint) wearing a garland or Kantha of 32 beads of Gauri Shankar, becomes Lord Shiva incarnate, it is believed. When any recommendation is in need of a synergistic enhancement to accelerate the effects of the Mala design, Gauri Shankar is recommended and is added directly on the back of the neck over the spine where the Kundalini flows.
