Why does Lord Shiva wear a crescent moon on his head?

Answer 1

Shiva grabbed the moon and chipped a piece off and placed it in his hair, so he is the god of the moon. That started when shiva first saw the moon so no body really chipped it to be the moon god but shiva saw it first. There are diffrent ways how he got them and make sure you dont write shiva is a girl he is not.

as crescent moon always become full moon , like once you experence soul (soul and body sepration) you will registered to become God .

Answer 2

Crescent moon: Shiva bears on his head the crescent moon. The epithet Chandraśekhara(Sanskrit: चन्द्रशेखर "Having the moon as his crest" - chandra = "moon", śekhara = "crest, crown") refers to this feature. The placement of the moon on his head as a standard iconographic feature dates to the period when Rudra rose to prominence and became the major deity Rudra-Shiva. The origin of this linkage may be due to the identification of the moon with Soma, and there is a hymn in the Rig Veda where Soma and Rudra are jointly implored, and in later literature, Soma and Rudra came to be identified with one another, as were Soma and the moon. The crescent moon is shown on the side of the Lord's head as an ornament. The waxing and waning phenomenon of the moon symbolizes the time cycle through which creation evolves from the beginning to the end. Since the Lord is the Eternal Reality, He is beyond time. Thus, the crescent moon is only one of His ornaments.

CRESCENT MOON AND SHIVA:Shiva, like any other Hindu god, is made of two elements.

1. Saguna Brahman - the facilitating force

2. Nirguna Brahman - the retarding/ controlling force.

Vishnu is the preserver and thus no effort is needed to control the Vishnu force.

In contrast, Shiva force is more difficult to control and Shiva is well known for his anger.

When it goes out of control the simplest way of controlling the Shiva force is blocking it with another thought using the Nirguna component (Parvati).

The crescent moon symbolizes this mechanism of Vighna or competitive blockade to control the mighty Shiva force.

The crescent moon on Shiva's head is moon during an eclipse. The eclipse symbolizes overlapping of two actions.

It must be mentioned here that this mechanism evolved into another distinct god, Ganesha, who is obviously considered as son of Shiva and Parvati.
