The entire day is spent at the Feet of the Lord. Continuous worship of the Lord necessitates the devotee's constant presence in the place of worship. Motion is controlled. Evils like lust, anger, and jealousy, born of Rajas are ignored and subdued. The devotee observes vigil throughout the night and thus conquers Tamas also.
Constant vigilance is imposed on the mind.
Every three hours a round of worship of the Shiva Lingam is conducted. Shivaratri is a perfect Vrata. The formal worship consists of bathing the Lord. He is burning with the fire of austerity. He is therefore best propitiated with cool bathing.
