In Indian culture every
lunar day carries some importance. For example fourteenth day of Krishna paksha
of every lunar month is called shivaratri. In one lunar year there are 12 shivaratri.
Out of all these 12 shivaratris, one that occurs in the month of Maagh is considered very special and is called Mahashivaratri – the great
night of Lord Shiva.
Additionally, as per
Shripad Shrivallabh Charitamrut, Mahashivaratri that falls on Tuesday is
considered as very auspicious.
Lord Shiva is considered
as a god who destroys. What does he destroy? He destroys the effects of great
sins of his devotees, the effects that otherwise can become the cause of
suffering.
In general one should
worship Lord Shiva on every day. However if it is not possible, at least on Mahashivaratri
it is recommended that one should worship Lord Shiva by chanting his holy name while
keeping vigil throughout the night. By doing this it is believed that one can
not only get rid of great sins but also sow the seeds for new auspicious vibrations
that can give perpetual joy and peace of mind.
