Happiness, unhappiness, realism, idealism, theism, atheism, etc. are all very superficial phenomena that are not at all on the level of clarity and ignorance. The source of consciousness is clarity. There is no time and space in clarity or clear light; all concepts of time and space arise from ignorance. However, in the brief moment when ignorance is first produced from clarity, there is no concept of time and space either. Just as in the Big Bang, there is no physical matter in the instant following the explosion, only later is energy produced from empty space; when the energy reaches a certain density, a fundamental particle is produced. From this fundamental particle, all kinds of matter are then formed. In the same way, from clarity, fundamental ignorance is produced, that is, consciousness — which is something undulating and capable of thinking and discriminating between events -- is formed. After that, a fundamental particle is instantly produced; all kinds of matter are then formed, followed by the formation of the earth and celestial bodies. Ignorance is just like energy; how things are formed from energy that is unobstructed by matter and how the world is created from ignorance are astonishingly similar.

幸福、不幸，唯物、唯心，有神、无神等等，都是最表面的现象，根本没有涉及到光明与无明的层面。意识的源头，就是光明。在光明当中，没有时间、空间。所有的时间和空间，都是从无明当中分出来的。从光明当中产生无明的初期，在短短的时间当中，也没有时空概念。就像大爆炸的瞬间，没有任何物质，之后才从真空当中，产生了一种能量，当能量的密度达到一定程度的时候，从能量当中，便形成了一个基本的粒子。之后，又从基本的粒子，变成我们所看到的形形色色的物质。同样，从光明当中产生原始无明，也即产生有波动的，可以思维、判断的意识之后，立即形成了基本的粒子，形成各种各样的物质，此后又形成山河大地、日月星辰等等。无明就像能量一样，从没有质礙的能量聚集成物质的过程，与无明产生世界的过程有着惊人的相似。

In Tibetan Buddhism, the Kalacakra Tantra describes three different worlds — external, internal, and secret — and their connection to one another. The external is the universe, including the solar system, Milky Way, etc.; the internal is the physiology of the human body; the secret is the mind. It is explained that our spiritual world is a universe; the structure of our body is a universe; the universe outside is also a universe. All three are closely connected. To a certain degree, they affect one another.

在藏传佛教的《时轮金刚》里面，描述了外在的宇宙世界，内在的人体结构，以及更深层的意识结构，并阐明了外内密三层宇宙之间的关系。外，就是外在宇宙，包括太阳系、银河系等等；内，就是人体结构；密，就是意识。其中讲到：人的精神世界，是一个宇宙；人体同样也是一个宇宙；外面的宇宙，也是一个宇宙，这三者有着密切的关系。在某种程度上，它们会相互影响。

In our present culture, research studies on the mind tend to be overlooked; the studies which are available usually do not treat the subject in depth. Yet, many of the problems human beings encounter come from the mind. What we feel inside is often unrelated to external circumstances.

现代文明往往比较忽略意识方面的研究，即使有一些研究和探求，也都是比较表层的。但人类的很多问题，却是从意识当中产生的。很多内心的感受，和外在的客观因素完全没有关系。
