In general, Buddhism embraces the idea that suffering arises from confused states of mind and attachment to the notion that things are permanent. Happiness can be achieved by practicing virtue and performing positive actions, which are said to be repaid through karma.

Dec. 8 is Bodhi Day, which marks the enlightenment of Siddhartha Gautama and his transition to the Buddha. According to tradition, he abandoned ascetic practices and resolved to meditate until he discovered the root of suffering.

It is said that in the first stage of Siddhartha's meditation, he accessed all of his past thoughts and deeds. This reflection led to the establishment of the cycle of rebirth, as he realized that he had been and would continue to be reincarnated many times.

Finally, after further contemplating cause and effect, Siddhartha created the Four Noble Truths. This concept revolves around the idea that suffering can be ended by ridding oneself of all attachment to desires.

After this third revelation, Siddhartha's enlightenment was complete and he achieved nirvana. This idea is the main cause for celebration of the holiday, as it is a central concept. Services and traditions vary among Buddhist sects, but many adherents observe the day's significance with additional meditation, studying the Dharma, and performing kind acts for others.
