As human beings we are gifted with this wonderful human intelligence. Besides that, all human beings have the capacity to be very determined and to direct that strong sense of determination in whatever direction they like. So long as we remember that we have this marvellous gift of human intelligence and a capacity to develop determination and use it in positive ways, we will preserve our underlying mental health.
Realizing we have this great human potential gives us a fundamental strength. This recognition can act as a mechanism that enables us to deal with any difficulty, no matter what situation we are facing, without losing hope or sinking into feelings of low self-esteem.
His Holiness the Dalai Lama
Action is being truly observant of your own thoughts, good or bad, looking into the true nature of whatever thoughts may arise, neither tracing the past nor inviting the future, neither allowing any clinging to experiences of joy, nor being overcome by sad situations. In so doing, you try to reach and remain in the state of great equilibrium, where all good and bad, peace and distress, are devoid of true identity.
Any attempt to capture the direct experience of the nature of mind in words is impossible. The best that can be said is that it is immeasurably peaceful and, once stabilized through repeated experience, virtually unshakable. It's an experience of absolute well-being that radiates through all physical, emotional and mental states - even those that might ordinarily be labeled as unpleasant.
We must understand that Buddha nature and its wisdom are inherent in our minds. It is extensively explained by many great scholars and masters, but it is very simple. It is just that awareness
that engages in all these activities, worldly or dharmic. It is the one who thinks "I must do this, do that, go here or there," or the scientists building planes and improving the world doing
this and that. It is just that awareness engaging in all these activities and doing all these things that we must recognize.
If we ride the horse of self-grasping and merge the mind with self-grasping, we will only go down further and further into samsara — we will have to continue wandering in samsara. But if we ride the horse of loving-kindness and compassion we will go more and more through the enlightened qualities of the Buddha; the nirmanakaya, then the sambhogakaya, then the dharmakaya — we will go up to complete enlightenment.
Another example is like a big tree. The lower part, the roots, represents the lower realms and self-grasping, the pain of self-grasping. If there is self-grasping we will always abide at the lower part of the tree. But if we give rise to the altruistic mind then we go up to the higher parts of the tree — the branches, the foliage, the leaves, the flowers and fruits and so on. There is still just one tree, one single ground, but if we abide at the bottom we experience great suffering and great difficulty from the self-grasping mind, but if we go up we bring about the benefit of others and our own happiness. The basis, the ground, is a single one — buddha nature.
