Sankaracarya's Vivekachudamani 489

धन्योऽहं कृतकृत्योऽहं विमुक्तोऽहं भवग्रहात् ।

नित्यानन्दस्वरूपोऽहं पूर्णोऽहं त्वदनुग्रहात् ॥

dhanyo'haṃ kṛtakṛtyo'haṃ vimukto'haṃ bhavagrahāt |

nityānandasvarūpo'haṃ pūrṇo'haṃ tvadanugrahāt ||

(Sankaracarya's Vivekachudamani 489)

Blessed am I, have reached the fulfillment of my life and am free from the jaws of transmigration. I am the embodiment of eternal Bliss, I am the Infinite, all by your Grace.

Sripad Sankaracarya is glad and blessed that he is very fortunate that he is free from the clutches of birth and death. He will live eternally with the Supreme Personality of Godhead. Not everyone can know in advance that they are going to the Lord or Moksha but in this verse Adi Sankaracarya is confident.
