This is the MerKaBa or Shatkona:
The Shatkona (षट्कोण) is a symbol used in Hindu yantra; a “six-pointed star” is made from two interlocking triangles; the upper stands for Shiva, Purusha, the lower for Shakti, Prakriti. Their union gives birth to Sanat Kumara, whose sacred number is six. The Shatkona represents both the male and female form, as a symbol of the divine union of masculine and feminine and as a source of all creation; more specifically it is supposed to represent Purusha (the supreme being), and Prakriti (mother nature, or causal matter).
TLDR: Union of Shiva and Shakti; or the alchemical marriage of fire and water elements.
