People pass on from one life to another according to the Buddhists and this according to them is the cycle. A being does not get free from the cycle of life until they live a pure sin-less life. And the living conditions of the next life of a being depends on how the being is carrying out his present life. When a person dies, according to the Buddhist customs certain rituals need to be performed to get the person ready for the next part of his life. According the Buddhists the corpse is either cremated or fed to the vulture. The Mahayana sect also follow the rituals where they have to expose the corpse to some natural entity like water, air or land. For example corpses are left in the woods or in particular places like river banks where they will get consumed by the forces of nature and their soul will move onto the next journey. The mandai columbarium which is a columbarium and crematorium in the mandai region of Singapore provide excellent facilities to perform the last rites of your loved ones. According to the Buddhists if a person can get rid of passion, aversion and ignorance their lives, then they achieve nirvana and get freed from the cycle of rebirth. These are called the ‘three fires’ or life that burn your life out and lead to an unfulfilled life. A Buddhists ultimate goal is to attain nirvana and nirvana comes under The Third Noble Truth, under the Four Noble Truths of Lord Buddha. Lord Buddh had left his life of comfort at the court to find the answer to all his queries, he had forgotten about worldly possessions and comfort and that is what Buddhists are meant to do in order to attain nirvana. Haven’t you seen in the movies that monks who live in monasteries live with nothing but just a red cloth wrapped around them and don’t believe in any kind of cravings.
There are two types of nirvana, one is the remainder nirvana and another is the non-remainder nirvana or the final nirvana. The great Lord Buddha is said to have achieved both but according to the Mahayana sect the final goal is to not attain nirvana but to attain Buddhahood where you keep on talking rebirths and help people to attain nirvana.
Nirvana is common in other religions too other than Buddhism like Hinduism and Jainism. Nirvana basically means to get freed from the cycle of rebirth and suffering. Later many new concepts were interpreted by various prophets as to what does nirvana exactly mean. According to interpretations made late nirvana means to live with any kind of emotion like love, greed, expetations and one has to abandon ones desires to attain nirvana. You need to remove yourself from the forest of defilement to attain complete nirvana.
Nirvana was once connected to immortality or attaining a medium where there is no death and many believed that Lord Buddha was a greater being than all of us.
