People can spend their entire life searching for enlightenment outside, travelling the whole world from the bottom of the oceans to the top of the mountains - they can search as much as they like, but it won't be found anywhere other than inside that which is doing the searching.
Without calmness of mind, it is very hard to have a sense of delight. Without this sense of delight, there is no genuine compassion. If we are totally preoccupied with our own experience - how I feel, what my problem is, and so forth - there is no chance at all for us to care about how others feel. There is simply no room for compassion.
There are different levels of faith. First, "clear faith" refers to the joy and clarity and change in our perceptions that we experience when we hear about the qualities of the Three Jewels and the lives of the Buddha and the great teachers.
"Longing faith" is experienced when we think about the latter and are filled with a great desire to know more about their qualities and to acquire these ourselves.
"Confident faith" comes through practicing the Dharma, when we acquire complete confidence in the truth of the teachings and the enlightenment of the Buddha.
Finally, when faith has become so much a part of ourselves that even if our lives were at risk we could never give it up, it has become "irreversible faith."
Dilgo Khyentse Rinpoche
Unless one is omniscient or at least enjoys some degree of clairvoyance, no one can judge others. One can see how others appear and how they are behaving, but not who they are or why they are behaving in a particular manner. For example, enlightened ones such as buddhas, bodhisattvas, and sages appear in peaceful forms and wrathful forms, but all their activities will be for serving others with love. This is why the fully enlightened Buddha said, “Apart from myself and those like me, no one can judge another person.”
