One of the most inspiring writings I know is a section entitled The Disciple Rejoices. It's near the end of The Crest Jewel of Discrimination, called Vivekachudamani. It was written by Shankara some 1200 years ago. After Self-Realization, the student cries out in joy about his experience of the union of his individual soul, Atman, with the Absolute, Brahman.
