Shivratri is the time when Shiva takes a rest. Shiva rests for one 'prahar' (three hours) of the night. This 'prahar' is referred to as the Shivratri. When Lord Shiva takes rest, the function of 'Shivtatva' (Shiva Principle) ceases, i.e. Lord Shiva goes into a meditative state. Shiva's meditative state is the time when He is engrossed in His own spiritual practice. During that time, the 'Shivtatva' does not accept any tamogun (most base of the 3 elements in us - sattva, raja & tama) or any halahal (venom churned from the ocean) coming from the Universe. As a result, the ratio of halahal or the pressure of the negative energies increases. For protection from this pressure, things like 'bilva patra', white flowers, 'rudraksha' beads etc are offered to Lord Shiva. These things attract the 'Shivtatva' from the atmosphere, thus providing protection from the increasing effect of the negative energies. The Earth is a gross object. Gross objects have very low velocities i.e. they require more time to cover a specific distance in space. Gods on the other hand, are subtle hence they are capable of traversing space within a few seconds. That is why one year on the earth is equivalent to just one day of heaven.

Some unique attributes

1. Physical attributes

a. Ganga : Just as the sun is the focal point of the solar system and the soul that of the body, the focal point of divine consciousness (chaitanya) in every object and pure particles (pavitrakas) is ga-aum. The flow from which ga-aum originates is gan gaha = Ganga. Ga-aum flows from Shiva's head. This is called the descent of the Ganga from Shiva's head. Since the river Ganga has a fraction of the principle of the spiritual Ganga, no matter how polluted it becomes, its purity is perpetually retained. Hence, when compared to any other water in the world, the water from the Ganga is the purest. This is realised not only by those who can perceive the subtle dimension but also by scientific researchers.

b. Moon : Shiva adorns the chandra (moon) on His forehead. The point where the three frequencies - affection (mamata), mercifulness (kshamashilata) and motherly love (vatsalya) originate is referred to as the chandra (moon). Thus, one can conclude that chandrama (the moon principle) is the state in which the three attributes of affection, mercifulness and motherly love are present.

c. Third eye : Shankar is three-eyed, i.e. He can perceive events of the past, present and future.According to the science of Yoga the third eye means the Sushumna nadi (channel).

d. Serpent : One of the Names of Lord Shankar is Bhujanga-patihari. Bhujang means a serpent or pure particles (pavitrakas), pati means the nurturer and hari means one with a garland around His neck. Bhujangapatihari thus means the One who nurtures pure particles and wears them like a garland. Various serpents represent groups of pure particles. Though externally they appear like serpents, internally they are a kind of ladder. To make spiritual progress one has to climb up holding onto the tail of the serpent. Lord Shankar adorns serpents at nine points on His body - one on the head, one around the neck, one on each arm, one on each wrist, one around the waist and one on each thigh. This implies that His body is comprised of pure particles or that serpents of pure particles play all over the body of Lord Shankar who has the universe as His form.

2. Spiritual attributes

a. One performing severe austerities and the great yogi

Shiva is always seated in a bandha or a mudra. His temperature rises due to heat generated by performing severe austerities; Hence, He uses the Ganga, the moon and serpents which endow a cooling effect and lives on the snow-clad Kailas mountain.

b. Short tempered

If someone disturbs His meditation the radiance generated by spiritual practice will be suddenly expelled and whoever is in front of Him will not be able to tolerate it, and gets destroyed. This is referred to as being 'reduced to ashes by Shankar's opening of the third eye'.

c. One who is willing to undergo any distress for the sake of imparting happiness to others

The poison generated during the churning of the celestial ocean (samudramanthan) was burning the entire Universe but no deity came forward to accept it. At that time Shiva drank that poison and saved the world from destruction.

d. One who has both, deities and demons, as His worshippers

Neither did demons like Banasur, Ravan, etc. worship Lord Vishnu nor did Lord Vishnu bestow any boon upon any demon. However, they worshipped Lord Shiva who blessed them.

e. Master of the spirits

Since Lord Shiva is the master of spirits, His worshippers are generally not possessed by them.
