Siva Bhujangam

यतोऽजायतेदं प्रपञ्चं विचित्रं
स्थितिं याति यस्मिन्यदेवान्तमन्ते ।
स कर्मादिहीनः स्वयज्ज्योतिरात्मा
शिवोऽहं शिवोऽहं शिवोऽहं शिवोऽहम् ॥

yatO ajAyate idam prapancham vicitram

SivOham SivOham SivOham SivOham

From where this wonderful world originates,  in which it is sustained, into that it merges in the end; THAT which has no actions etc., (includes thoughts, words as well) the self effulgent "Atma"; I am THAT Shiva (Atma); I am that Shiva; I am THAT I AM!
