which is shivas beloved geometric pattern?

Lord Shiva is closely associated with the Shiva Yantra (also known as the Shiva Linga or Linga Yantra), a sacred geometric pattern representing his cosmic energy and consciousness. Another highly revered geometric pattern in Shaivism is the Sri Yantra (or Shri Chakra), although it is primarily connected with Goddess Tripura Sundari, it is often worshipped in conjunction with Shiva as it represents the union of Shiva (consciousness) and Shakti (energy).

The Shiva Linga itself is considered a powerful geometric and symbolic form, representing the formless aspect of Shiva and the infinite creative potential of the universe.

In summary, the Shiva Yantra and the Shiva Linga are most beloved and significant geometric patterns associated with Lord Shiva.
