Living Master is a term which distinguishes a living spiritual teacher from one who has already left his physical form (i.e., died). Certain esoteric spiritual movements, notably Sant Mat and Surat Shabd Yoga, consider a living spiritual adept to be essential, and critique the world religions as mere shells where a living master (who founded the religious movement) has been replaced with a scripture, statue, effigy, or other symbol. Just as an example of the current usage, Sant Baljit Singh is described by his disciples as a Living Master, while Jesus Christ or the Buddha are examples of past Masters or Masters out of date as per Sant Mat.[1]
