The couple is often depicted in the Puranas as engaged in dalliance or seated on Mount Kailash debating concepts in Hindu theology. They are also depicted as quarreling. In stories of the birth of Kartikeya, the couple is described as love-making; generating the seed of Shiva. Parvati's union with Shiva symbolises the union of a male and female in ecstasy and sexual bliss. In art, Parvati is depicted seated on Shiva's knee or standing beside him (together the couple is referred to as Uma-Maheshvara or Hara-Gauri) or as Annapurna (the goddess of grain) giving alms to Shiva.
