Indian Iron Tantric Lingam

The river shaped the idea. A single red line crosses the stone like a horizon.

This Tantric lingam comes from the Narmada River in India. Its age is indeterminate, and its material is quartz crystal with iron oxide inclusions. Hindu devotees have long revered egg-shaped stones from the Narmada as natural emblems of Shiva, and in Tantric practice the lingam is also a focus for meditation. The smooth, polished surface shifts from olive to slate, clouded with rust and pale flecks. One band of deep red circles the middle. Just under eleven inches high and six and a quarter across.

It asks for little beyond a quiet place to stand.
