Shatkona represents the union of male and female.
The Shatkona (षट्कोण) is a symbol used in Hinduyantra; a “six-pointed star” is made from two interlocking triangles; the upper stands for Shiva, Purusha and fire, the lower for Shakti, Prakriti and water. Their union gives birth to Sanat Kumara, whose sacred number is six. The Shatkona represents the both the male and feminine form, as a symbol of the divine union of masculine and feminine and as source of all creation; more specifically it is supposed to represent Purusha (the supreme being), and Prakriti (mother nature, or causal matter). Often this is represented as Shiva / Shakti. It is often referenced that the Satkona/Shatkona is the symbol of the Hindu deity known as Sanat Kumara (and by many other names).
The Shatkona is a hexagram and is associated with the son of Siva-Sakthi, Lord Murugan.
