Namami Shamishan Nirvan Roopam
Vibhum Vyapakam Brahma Veda Swaroopam
Nijam Nirgunam Nirvikalpam Nireeham
Chidakasamaakasa Vasam Bhajeham
Niraakara Monkaara Moolam Thureeyam
Giraa Jnana Gotheethamesam Gireesam
Karalam Maha Kala Kalam Krupalam
Gunaa Gara Samsara Param Nathoham
Thushaaraadhi Sankasa Gowram Gabheeram,
Mano Bhootha Koti Prabha Sree Sareeram,
Sphuran Mouli Kallolini Charu Ganga,
Lasaddala Balendu Kante Bhujanga
Chalath Kundalam Bru Sunethram Vishaalam,
Prasannananam Neela Kandam Dhayalam,
Mugadheesa Charmambaeam Munda Malam,
Priyam Shankaram Sarva Nadham Bhajami
Prachandam Prakrushtam Prakalbham Paresam,
Akhandam Ajam Bhanu Koti Prakasam,
Thraya Soola Nirmoolanam Soola Panim,
Bhajeham Bhavani Pathim Bhava Gamyam
Kalatheetha Kalyani Kalpanthakari,
Sada Sajjananda Datha Purari,
Chidananda Sandoha Mohapahari,
Praseeda Praseeda Prabho Mamamadhari
Na Yavad Umanada Padaravindam,
Bhajantheeha Loke Pare Vaa Naraanaam,
Na Thath Sukham Shanthi Santhapa Nasam,
Praseedha Prabho Sarva Bhoothadhivasam
Na Janami Yogam, Japam, Naiva Poojaam,
Nathoham Sada Sarvadha Shambhu Thubhyam,
Jara Janma Dukhogha Thathpyamanam,
Prabho Pahi Aapannamameesa Shambho
Rudhrashtakam Idham Proktham Viprena Hara Thoshaye,
Ye Padanthi Naraa Bhakthya Thesham Shambhu Praseedathi
Vibhum Vyapakam Brahma Veda Swaroopam
Nijam Nirgunam Nirvikalpam Nireeham
Chidakasamaakasa Vasam Bhajeham
Niraakara Monkaara Moolam Thureeyam
Giraa Jnana Gotheethamesam Gireesam
Karalam Maha Kala Kalam Krupalam
Gunaa Gara Samsara Param Nathoham
Thushaaraadhi Sankasa Gowram Gabheeram,
Mano Bhootha Koti Prabha Sree Sareeram,
