Shivratri commemorates the descent of Supreme Light, jyotirling Shiv, to end the darkness of ego, anger, avarice and attachment from human mind and life. Even the term 'Shivratri', comprising two words, 'Shiv' and 'ratri', respectively, refers to 'self- effulgent point light' and 'night or darkness'. Maha Shivratri thus, signifies the rise of spiritual Sun, incorporeal God Shiv and his descent on earth, in the corporeal medium of Prajapita Brahma, to dispel the deep darkness of inertia, ignorance and ineptitude from our minds, through teachings of godly knowledge and rajyog meditation.
