There is only one way of attaining liberation and of attaining the omniscience of enlightenment - following an authentic spiritual master. He is the guide that will help you to cross the ocean of samsara.
The sun and the moon are reflected in clear, still water instantly. Similarly, the blessings of all the buddhas are always present for those who have complete confidence in them. The sun's rays fall everywhere uniformly, but only where they are focused through a magnifying glass can they set dry grass on fire.
When the all-pervading rays of the Buddha's compassion are focused through the magnifying glass of your faith and devotion, the flame of blessings blazes up in your being.
Dilgo Khyentse Rinpoche
Even to learn worldly crafts, things we can understand by seeing them with our eyes, we need a teacher to show us.
So how is it possible that we, who have just come from the lower planes of existence, and are entering a path where we have never been before, could travel it without a guide?
Mesmerized by the sheer variety of perceptions,
which are like the illusory reflections of the moon in water,
Beings wander endlessly astray in samsara's vicious cycle.
In order that they may find comfort and ease in the luminosity
and all-pervading space of the true nature of their minds,
I generate the immeasurable love, compassion, joy and equanimity
of the awakened mind, the heart of bodhicitta.
