In the latter part of this period, during the rule of His Holiness the Great Thirteenth Dalai Lama, this eminent spiritual and temporal ruler of Tibet enacted many modifications in administrative policies in accordance with international customs. Based on the formats of previous Tibetan military flags, His Holiness improved upon them and designed the present, modern national flag. With an official proclamation, He declared that this would be the uniform, standard flag to be adopted by all Tibetan military defence establishments. Since the time of that proclamation, all Tibetan regiments have likewise adopted this flag as their standard. The colour scheme of the Tibetan national flag gives a clear indication of all aspects of Tibet in its symbolism such as the geographic features of the religious.
History attests to the fact that Tibet is one of the most ancient nations of the world.
Therefore, in all the three regions of Tibet, irrespective of caste and creed, this national flag inherited from our ancestors is universally accepted as a common, peerless treasure and even today still continues to be highly respected and esteemed as in the past. In the centre stands a magnificent thickly snow clad mountain, which represents the great nation of Tibet, widely known as the Land Surrounded by Snow Mountains. At the tip of the snow mountain, the sun with its rays brilliantly shining in all directions represents the equal enjoyment of freedom, spiritual and material happiness and prosperity by all beings in the land of Tibet. On the slopes of the mountain there proudly stand a pair of snow lions blazing with the manes of fearlessness, which represent the country's victorious accomplishment of a unified spiritual and secular life. The two coloured swirling jewel held between the two lions represents the peoples' guarding and cherishing the self discipline of correct ethical behaviour, principally represented by the practices of the ten exalted virtues and the 16 humane modes of conduct.
