In giving an overview of the Buddha dharma, as practised by the Tibetans, I generally point out that the Buddhism we practise is an integrated form comprising teachings of the low, Bodhisattva and Tantric vehicles, including such paths as the Great Seal. Because quite a number of people have already received initiations, teachings and so on, they might find it helpful to have an explanation of the complete framework.
We pass our lives very busily. Whether we behave well or not, time never waits for us, but goes on forever changing. In addition, our own lives continually move on, so if something goes wrong, we cannot repeat it. Life is always running out. Therefore, it is very important to examine our mental attitude. We also constantly need to examine ourselves in day to day life, which is very helpful to give ourselves guidelines. If we live each day with mindfulness and alertness, we can keep a check on our motivation and behaviour. We can improve and transform ourselves. Although I haven't changed or improved myself much, I have a continuing wish to do so. And in my own daily life, I find it very helpful to keep a check on my own motivation from morning until night.
During these teachings, what I will be describing is essentially a kind of instrument with which to improve yourself. Just as you might take you brain to a laboratory to examine your mental functions more deeply, so that you can reshape them in a more positive way. Trying to change yourself for the better is the point of view a Buddhist practitioner should adopt.
People of other religious traditions, who have an interest in Buddhism and who find such features of Buddhist practice as the meditative techniques for developing love and compassion attractive, could also benefit by incorporating them into their own tradition and practice.
In Buddhist writings many different systems of belief and tradition are explained. These are referred to as vehicles, the vehicles of divine beings and human beings and the low vehicle (Hinayana), the great vehicle (Mahayana), and the vehicle of Tantra.
The vehicles of human and divine beings here refer to the system which outlines the methods and techniques for bringing about a betterment within this life or attaining a favourable rebirth in the future as a human or god. Such a system highlights the importance of maintaining good behaviour. By performing good deeds and refraining from negative actions we can lead righteous lives and be able to attain a favourable rebirth in the future.
The Buddha also spoke of another category of vehicle, the Brahma vehicle, which comprises techniques of meditation by which a person withdraws his or her attention from external objects and draws the mind within, trying to cultivate single-pointed concentration. Through such techniques one is able to attain the highest form of life possible within cyclic existence.
From a Buddhist point of view, because these various systems bring great benefit to many living beings, they are all worthy of respect. Yet, these systems do not provide any method for achieving liberation, that is, freedom from suffering and the cycle of existence. Methods for achieving such a state of liberation enable us to overcome ignorance, which is the root cause of our spinning in the cycle of existence. And the system containing methods for obtaining freedom from this cycle of existence is referred to as the Hearer's or Solitary Realizer's vehicle.
In this system, the view of selflessness is explained only in terms of the person not of phenomena, whereas in the great vehicle system, the view of selflessness is not confined to the person alone, but encompasses all phenomena. When this view of selflessness gives rise to a profound understanding, we will be able to eliminate not only ignorance and the disturbing emotions derived from it, but also the imprints left by them. This system is called the great vehicle.
The highest vehicle is known as the Tantric vehicle which comprises not only techniques for heightening your own realization of emptiness or mind of enlightenment, but also certain techniques for penetrating the vital points of the body. By using the body's physical elements, we can expedite the process of realization, eliminating ignorance and its imprints. This is the main feature of the tantric vehicle.
I would now like to explain these points in greater detail from an evolutionary or historical point of view.
According to the viewpoint of the Kashmiri Pandit Shakyashri, who came to Tibet, Lord Buddha lived in India 2500 years ago. This accord with the popular Theravadin view, but according to some Tibetan scholars, Buddha appeared in the world more than 3000 years ago. Another group says it was more than 2800 years. These different proponents try to support their theories with different reasons, but in the end they are quite vague.
I personally feel it is quite disgraceful that nobody, not even among Buddhists, knows when our teacher, Shakyamuni Buddha, actually lived. I have been seriously considering whether some scientific research could be done. Relics are available in India and Tibet, which people believe derive from the Buddha, himself. If these were examined with modern techniques, we might be able to establish some accurate dates, which would be very helpful.
We know that historically the Buddha was born as an ordinary person like ourselves. He was brought up as a prince, married and had a son. Then, after observing the suffering of human beings, aging, sickness, and death, he totally renounced the worldly way of life. He underwent severe physical penances and with great effort undertook long meditation, eventually becoming completely enlightened.
I feel the way he demonstrated how to become totally enlightened set a very good example for his followers, for this is the way in which we should pursue our own spiritual path. Purifying your own mind is not at all easy; it takes a lot of time and hard work. Therefore, if you choose to follow this teaching you need tremendous willpower and determination right from the start, accepting that there will be many, many obstacles, and resolving that despite all of them you will continue the practice. This kind of determination is very important. Sometimes, it may seem to us that although Buddha Shakyamuni attained enlightenment through great sacrifice and hard work, we his followers can easily attain Buddhahood without the hard work and difficulties that he underwent. So, I think that the Buddha's own story has something to tell us.
According to popular legend, after his complete enlightenment, the Buddha gave no public teaching for 49 days. He gave his first discourse to the five who had formerly been his colleagues when he lived as a mendicant. Because he had broken his physical penances they had abandoned him and even after he had become totally enlightened they had no thoughts of reconciliation towards him. However, meeting the Buddha on his way, they naturally and involuntarily paid him respect, as a result of which he gave them his first teaching.
