He who liveth detached, Enshrining the One Lord in his mind, Who hopeth yet desireth not, Canst see as well as show The Unfathomable and the Unperceivable, Of such a one will Nanak be a slave. (GG, 938) In the Natha tradition, Charpat, is known to have been a disciple of Gorakhnath whose period falls somewhere in the llth to 12th century.
Guru Nanak whose period is much later must have therefore met some contemporary incumbent ofCharpat`s seat who also bore his name. Sixtyfour slokas attributed to Charpat are included in the Hindi work Natha Siddhon ki Baniyan some of them relating to the preparation of elixir to prevent disease and infirmity. Charpat is counted among Siddhas of the rasayana (alchemy) tradition.
