In my opinion, it is important that everyone should be free to practice any religion of their choice so long as it does not interfere with maintenance of law and order or challenge the rule of government.In the 4th century, Mahayana Buddhism became more popular due to Vietnam's proximity to China. Buddhism, in Vietnam, progressed rapidly during the reigns of the Ly (1009-1225 AD) and Tran Dynasty (1225 - 1400 AD). During this period Buddhism attained the status of state religion.
Some of the major principles of Buddhism include the Four Noble Truths, the Noble Eight fold Path, Refuge in Three Jewels, the Five Precepts and the Three Marks of Conditioned Existence. The Four Noble Truths of Buddhism teach that life is a suffering, there is a cause of this suffering, it is possible to put an end to this suffering and the Noble Eight fold Path is the means to end this suffering; Refuge in Three Jewels are the three components of Buddhism which protect a person from the unstable world as he progresses on the path to become a Buddhist. The Five Precepts lay down the moral conduct to make the world a better place to live. These precepts prevent Buddhists from indulging in deeds that restrict spiritual growth and cause harm to others. The Three Marks of Conditioned Existence explain that everything in this world is impermanent, without substance and full of suffering.
A fundamental belief of Buddhists is reincarnation. This is a concept where people are reborn after dying. In reincarnation, the individual may recur repeatedly, after which they can attain Nirvana – a state of liberation and freedom from suffering.
