Sarvajnatman, a well-reputed advaita Acharya of the 9th-10th century, was the author of samkshepa shArIraka. As the title indicates, this book is a brief presentation of Sankara’s sUtra bhAshya in four chapters corresponding to the four adhyAya-s of the brahma sUtra-s.Sarvajnatman sums up the essential nature of brahman in ten words. They are:nitya, suddha, buddha, mukta, satya, sUkshma, sat, vibhu, advitIya and Ananda(eternal, pure, knowing, free, true, subtle, existent, auspicious, without a second and infinite (or happy)).advaita teaches that you and brahman are one and the same. You being already brahman, the above ten words, therefore, describe you also. That means you, yourself, are Happiness. So Happiness should be known to you like you know the back of your hand. You do not have to search for or attain Happiness
