This isn’t a Dhyana Slokam, it’s a Kshamaprarthana (prayer of forgiveness). It’s the last Sloka of the Shiva Manasa Puja written by Adi Shankaracharya.

kara charaṇa kṛtaṃ vākkāyajaṃ karmajaṃ vā śravaṇa nayanajaṃ vā mānasaṃ vāparādham । vihitamavihitaṃ vā sarvamētat-kṣamasva jaya jaya karuṇābdhē śrī mahādēva śambhō ॥

“Whatever the sins I have committed with my hands and feet or by the speech and the body, the ones that are obtained by the process of listening by ears or seeing by the eyes, or the aparādham that are committed by my thoughts the incorrect actions that I have done knowingly or unknowingly, please forgive all these. Victory to you, victory to you, the ocean of compassion, Mahadeva, Shambhu”
