The lingam stone is a representation of the Hindu deity Shiva used for worship in temples. The lingam is often represented alongside the yoni, a symbol of the goddess or of Shakti, female creative energy.The union of lingam and yoni represents the "indivisible two-in-oneness of male and female, the passive space and active time from which all life originates". The lingam and the yoni have been interpreted as the male and female sexual organs since the end of the 19th century by some scholars. While practicing Hindus the lingam stands for the inseparability of the male and female principles and the totality of creation. The lingam stones are available in 10 different sizes.
