Application of the Three Seals in practice.VIETNAMESE TRANSLATE ENGLISH BY=VIETNAMESE BUDDHIST NUN=THICH CHAN TANH. Impermanence, Suffering and Anatta are the three essential characteristics of the teaching. Each dharma seal has a different role and function to identify Dharma. However, under the knowledge of dependent origination, the three dharma seals have a reciprocal relationship that is closely linked with each other. In the seal of impermanence which contains the imprint of suffering and non-self, the other two are the same. The Three Dhamma teachings, in addition to the function of evaluating the Dharma, also provide insight to illuminate reality in order to dispel confusion, craving, wrong views to get rid of all clinging to suffering, to attain peace and liberation. Once the human mind is tinged with attachment, then suffering comes into being. It is necessary to have correct awareness of the three dharma seals to assess the sutras and especially the application in the practice of reflecting on the five aggregates. All the suffering of beings is derived from attachments, attachments due to the wrong conception of an eternal, unchanging, eternal self. The two concepts that people are often tied to are "I" and "mine". The misconception that all living beings have a homogeneous nature or an eternal "soul" and the conservative viewpoint, opinion and assumption that we are always right in all cases is the basis for of suffering and hindering spiritual uplifting. The concept of "having an invisible invisible entity in each individual" has been present in most of the previous and contemporary religions of the Blessed One, while still having a strong influence in the spiritual life of humanity today. . Therefore, as long as man understands the world of phenomena and sentient beings which are inherently impermanent and non-self, then suffering and darkness are truly eliminated. The concept of "having an invisible invisible entity in each individual" has been present in most of the previous and contemporary religions of the Blessed One, while still having a strong influence in the spiritual life of humanity today. . In short, the three markings of Impermanence, Suffering and Anatta are the basic principles that define the Dharma, re-evaluate theories, views, and practice of Buddhism. Although the Buddhist scriptures are extremely diverse, the thought contained in them is still not outside the trajectory of the three dharma seals. At present, there are still scattered "sutras" of books handed down in the temples and Buddhist circles in the name of Buddhist sutras but lack of three Dharma markings, for example, the land of chauvinism, the apple army of the cheetahs ... Therefore, it is necessary to have proper awareness of the three dharma seals to evaluate the sutras and especially to apply in the practice of contemplating the five aggregates. All the suffering of beings is derived from attachments, attachments due to the wrong conception of an eternal, unchanging, eternal self. "I" and "mine" are the causes of total conflict in all areas of human life. Therefore, the teaching of the three seals is the key to opening the door of liberation, as the foundation for the transformation of defilements, the attainment of insight and spiritual sublimation.END=NAM MO SHAKYAMUNI BUDDHA.( 3 TIMES ).GOLDEN AMITABHA MONASTERY=VIETNAMESE BUDDHIST NUN=THICH CHAN TANH.AUSTRALIA,SYDNEY.16/4/2021.
