Subramania or Shanmukhan (six faced) is the youngest son of Siva-Parvati family. The first offspring from Siva (Atma) and Parvati (Maya) is Ganapathy. The mind emerges from this union. Then comes ego (the I-feeling) and the consciousness of time and space. Subramani represents the ‘year’ (time) and His faces can be interpreted as the six seasons. Among these seasons Subramania represents the spring season. Time or Kaala, depends on the sun. When the earth rotates on its axis we experience night and day. The seasons evolve with the revolution of the earth round the sun.
Further, based on the movements of the moon, we have the dark and light sides of he month (Krishna-paksha and Shukla-paksha) Thus a lunar month has two sides (fortnights) and then we have a lunar year.
In fortunate times everything turns out to be good. For this (to get good times) we pray to God of time (Kaala). Kaala (the God of Death) is a manifestation of Time. Thus, Kaala is associated with many concepts, in Hindu Scriptures. The feminine form of Kaala is Kaali. The most beautiful time of the year is spring, which represents Subramania.
We have no idea when Time started and when it will end. In a sense, Time is endless and eternal. The colour of the eternal sky and sea is blue. Hence Kaali has blue colour.
Time has evolved from Paramatma (The Supreme Self). Therefore Kaali is considered as Siva’s daughter. Time consumes and destroys everything. The very form of Kaali as a destroyer and sustainer of the world, clarifies this point.
Spring is the most beautiful season of the year. Therefore, the peacock, a beautiful bird, has been chosen as the vehicle of Subramania. Time moves according to the state of our mind. When we are happy we are not aware of the passage of time. When we are sad, we feel that time is moving slowly. Therefore, our ancestors decided on the peacock, which can walk slowly or fly fast, as the vehicle of Lord Subramania.
The peacock is perched on a serpent. The serpent is the real symbol of time, since Time (Kaala) symbolizes death, just as the serpent is a cause of death. The serpent can move only forward. Since Time also moves only forward, it is an important symbol of Time.
Man is bound by Time. The God of Death (Yama or Kaala) also binds the dead with his rope. We may infer that the consort of Subramnia, Valli (literally means rope) represents this rope. As mentioned earlier, time depends on the sun. The Vel (single pointed spear) in the hand of Subramania can be considered as the ray of the sun.
We can assume that the worship of Subramania has its origin in the worship of sun. The word savitr in the Gayatri Mantra also represents the sun.
