From guru devotion comes correctly devoting to the virtuous friend with thought and action, and everything comes from that. The guru is White Tara for long life; the guru is Manjushri to achieve wisdom; the guru is the yidam, from which through prayers one achieves attainments; the guru is also the protector from whom you receive protection, who dispels interferers; the guru is also Dzambala, from whom with devotion, seeing him as the Buddha and correctly devoting oneself, then one gets all wealth, all prosperity, for one’s own conditions needed to help other sentient beings, to teach them; the guru is the controlling deity, like Hayagriva or Mahakala, eliminating obstacles, to control your mind, the delusions, and to achieve enlightenment, the subtle mind, and then to benefit other sentient beings.
The guru is everything. From guru devotion, you achieve everything—that’s the main cause, the main source. It’s like a big department store where you can get everything! So, the guru is everything.
