The study of traditional Tibetan opera needs to be  raised from the level of artistic skills to the level of philosophy; we need to discuss its essential and aesthetic features， explore its significance and value for the Tibetan， and reflect its ethnic spirit and value. As an aesthetic category， “tension” in the aesthetic activities of drama not only refers to the aesthetic tension of the plot constructed by dramatic conflicts， but even more lies in the force of the aesthetic impact produced by the collision between various elements surrounding the drama. As one of the favorite art forms of Tibetans， the beauty of traditional Tibetan opera is not only reflected in its stylized form and its content with rich meaning， but the beauty is seen more in the art space with its strong aesthetic tension constructed from the mutual confrontations， conflicts and contradictions between the elements in the opera. All of these enable the recipient to resonate with it and receive a spiritual baptism in the aesthetics of the art.
　　The aesthetic tension of traditional Tibetan opera is mainly reflected in the following five aspects：
　　1）Smallness and greatness： the sublime beauty formed by the great contrast between the subject and the object. In traditional Tibetan opera， the great contrast between the subject and the object produces a sublime beauty， which reflects the surmounting spirit of the Tibetan people who will never give in. It is a kind of consolation and peace of mind after overcoming and conquering fear. Therefore， the aesthetics of traditional Tibetan opera is a kind of aesthetic feeling that is full of surprise and respect; they reflect the emotional experiences of the Tibetan people after internalizing the vitality in their souls， and they are also a kind of spirituality that lies beyond physical bodies and senses.
　　2）Dharma enlightenment and secular emotions： the brilliance of human nature that is highlighted in the narrative logic of Buddhism. Traditional Tibetan opera adopts Buddhist logic to narrate the story， which embodies the life attitudes and spiritual beliefs of the Tibetan people， as well as their cognition and pursuit of the truth， kindness and beauty. However， the character development is too singular，  and also lacks change.
