His elder brother, the god of the sea, ruled the sea in the west, and Kupila, the god of wealth, ruled the Yaksha kingdom in the north.

The Four Heavenly Kings in ancient Indian mythology are the four guardian gods who guard the four states of the four directions.

Kubera is another name for King Bishamon. Originally the Hindu god of wealth, the guardian of all wealth in the world, the protector of the north, and the king of Yaksha and Kinara.

It is important to note that Kupila is the guardian and administrator of all the gods of wealth in the world, and he is the king of the medicine fork and kinara. In Buddhism, the medicine fork generally has two roles: the god of wealth and the protector of the Dharma. And like the Yellow God of Wealth, the General of Baoxian, the General of Loose Fat, the General of Shensha, etc., are all subordinates of King Bishamen.

In Brahmanism, the king is derived from the god Kupila in Hindu mythology. After a thousand years of asceticism, Lord Kupila received the position of patron saint of the north from his grandfather, Brahma, the god of creation, and thus received the flying chariot "Pushaboka", which symbolized wealth, and established himself as the "god of protection and wealth". Therefore, it is also known as Shi Caitian.

Because he once led his Yaksha and Vishnu to defeat the demon king Ravana, he has been revered as a god of martial arts and a god of war. According to legend, the king of Duowen often supports the Dojo, so he often hears the Dharma of Ruwen, so he is named Duowentian, and is the god of knowledge.

In the Tang Dynasty of China, the Tang Ming Emperor had been able to pacify many troubles because of the blessing of the King of Heaven, so he was specially ordered to enshrine it, and the army of the Tang Dynasty drew the banner with the image of the King of Heaven, called the Flag of the King of Heaven, in order to bless the prosperity of Wuyun.

After Buddhism was introduced to Japan, many military generals in Japan believed in Buddhism during the Warring States Period, and the famous "Bishamon Heavenly Lord" - Echigo's military god Uesugi Kenshin also appeared, claiming to be the incarnation of Bishamonten. His military flag bears the inscription "Bi" (a variant of "Bi").

Bishamonten is also included in the "Seven Gods of Good Fortune" of Japanese folk beliefs. According to Japanese folklore, there was once a temple dedicated to the "Bishamon Heaven", where monks could get food by throwing an empty bowl into the air.

The above is a brief record of the evolution of King Bishamen from Hindu mythology to Han Buddhism and Japanese Buddhism. In Tibetan Buddhism, the King of Treasures, is an important protector of the god of wealth.

He is one of the four heavenly kings, as the emperor Shakti's ministers, in order to be able to protect the world, also known as the protector of the world, the Sanskrit name Bishamen, translated as many smells, the name of its blessings, heard in the four directions.

The Treasure King is one of the transformed incarnations of the King of Bishamon, manifesting as the protector of the world, and he resides in the Pure Land of Vajrapani Bodhisattva, the Northern Willow Leaf Palace. It has a deep relationship with Vajrapani Bodhisattva and belongs to the subordinates of Vajrapani Bodhisattva. At the same time, it has great merit, specializing in protecting the wealth of sentient beings, and also serving as a treasurer.

The Treasure King has four princesses, four sons, and eight medicine forks for career achievement, bestowed on the eight dragon kings of treasure, five gods of wealth (yellow god of wealth, black god of wealth, red god of wealth, white god of wealth, green god of wealth) and endless heavenly dragons and eight tribes, various gods and other dependents.

As we can see, Kupila spread from India to Han China, Tibet, and Japan, with different identities, roles, and practices. From the perspective of Tibetan tradition, his dependents are immeasurable, and most of them are the characters of the god of wealth, such as the five surnamed gods of wealth, and the eight dragon kings in charge of wealth and power, etc., are all his dependents.

In Esoteric Buddhism, the King of Bishamen also has the family members of the eight great medicine fork generals, namely: Baoxian General, Manxian General, Zhongting General, Ying Nian General, Manman General, Wubi General and Miyan General. There are also twenty-eight messengers, who specialize in obeying the orders of the king of heaven and accomplishing various undertakings.

There is a red treasure king in Nyingmapa Gatuo Province, which is passed down by Guru Rinpoche, which is very special. There are many people practicing in the Golok area, and there are many fulfillments.

Sakyaba has a white treasure king, and in addition to blessings, the method of prolonging life is particularly good. It is the Sakya sect that does not share the treasure king.

There is a blue horse and red spear treasure king in the Jonang sect, which is the uncommon treasure king of the Venerable Taranatha, and his blessing power is extremely powerful, especially fast and powerful. In terms of speed, this statue is the first.

The Nyingma sect also has a statue of a horse holding a sword, and there is a translated simple offering text in Taiwan, in which the body shape is different.

Generally speaking, most of the people in Tibetan circles know that there are certain requirements for the Treasure Heavenly King Law to be corresponding. Because he is the protector of the Dharma and supports the practitioners' cultivation of the Dharma, the requirement is that the intention and precepts must be pure, otherwise it will be difficult to correspond.

The first thing to practice is to see the purity of the precepts, which is the origin of the first look of the Treasure King.

What to do in the family, in the family, the character must be correct, fair and just, righteous, and at the same time the profession must be correct, and you can't go astray, otherwise it is not good.

At the same time, when practicing externally, the Treasure King is also a very clean lord, and he should take more baths, wash his hands, face and teeth, and the cleanliness of his body and mind can correspond to the Treasure King. In the past, if you can take a bath often, it must be a rich and noble person who has a very good environment, and you don't have a bath in poor places.

Eating and lodging are also particular, and bowls with missing corners, incomplete cracked cups, food delivered by unclean people, and tea cannot be touched. In particular, murder and fornication.

Because of the strict requirements of the precepts of King Bishaman, some people often do not practice easily and are discouraged. And this is the requirement of the Vishamans after they spread from India to Tibet.

So, let's go back to the original point, that is, on the Indian side, the original role of the king of Bishaman, Kupila, may not have such requirements for precepts and all aspects, he is purely the king of medicine forks who guards wealth.

Why this is so has to do with the evolution of the gods and the flow of the law.

For many sources of the protector gods of the heavens, one is that the Buddha and Bodhisattva subdued the gods of the outer realms by decree the reincarnation of the Ming King, and then made them take refuge in the Three Jewels, receive the five precepts or tantric vows, and make a vow to uphold the Dharma and benefit sentient beings.

The second is that the Buddha and Bodhisattva directly incarnate as a foreign god, and then directly lead sentient beings as a god. First, to meet the worldly needs of sentient beings, and then step by step to the path to liberation.

For example, if the public worships the sun god, or a great god, the bodhisattva dwells in samadhi, directly incarnates as this god, gives the believers worldly wishes, and then guides them, abstains from killing, believes in cause and effect, and upholds the Dharma......

This is based on the convenience of great compassion and bodhichitta.

According to the History of Buddhism in India by His Holiness Tharanatha of the Jonang Sect:

In the east, there was a Brahmin named Siddha who enjoyed the same life as the Great King, and with his thousands of dependents, he devoted himself to the sun. At the time of his offering to the sun, the Sage Tidiga manifested a transfiguration from the center of the sun wheel, emitting a great light in front of him.

He also thought that it was the god of the sun, and he made offerings, and the Holy One spoke to him. When his faith was great, the Holy One reappeared and gave him the Dharma again.
