What is "shikshashtakam"

The Shikshashtakam ( IAST: ) is a 16th-century Gaudiya Vaishnava Hindu prayer of eight verses composed in the Sanskrit language. They are believed to be the only verses left personally written by Chaitanya Mahaprabhu (1486 – 1534) with the majority of his philosophy being codified by his primary disciples, known as the Six Goswamis of Vrindavan. The Shikshashtakam is quoted within the Chaitanya Charitamrita, Krishnadasa Kaviraja Goswami's biography of Chaitanya Mahaprabhu, written in Bengali. The name of the prayer comes from the Sanskrit words , meaning 'instruction', and aṣhṭaka, meaning 'consisting of eight parts', i.e., stanzas. The teachings contained within the eight verses are believed to contain the essence of all teachings on Bhakti yoga within the Gaudiya tradition.
