Sri Aurobindo's diary of his yogic practice between 1909 and 1927.

This two-volume record of sadhana contains fairly regular entries between 1912 and 1920 and a few entries in 1909, 1911 and 1927. It also contains related materials Sri Aurobindo wrote about his practice of yoga during this period, including descriptions of the seven "chatusthayas" (groups of four elements), which are the basis of the yoga of the Record.
