Root guru, root teacher / master. A practitioner of Vajrayana can have several types of root guru: the vajra master who confers empowerment, who bestows reading transmission, or who explains the meaning of the tantras. The ultimate root guru is the master who gives the 'pointing-out instruction' so that one recognizes the nature of mind [RY]
