Most religions in the world have beliefs regarding the afterlife. However, what Buddhists believe happens when we die is uniquely beautiful.
According to Buddhists, gradually, all of us will pass a path as a natural part of the cycle of life, death, and rebirth. According to them, death is not the final step; apart from that, it is still another step of a never-ending cycle. You see, The Buddhists trust that death is simply called the physical end of our mortal figure. Except our wishes to hold onto this physical body, just as everything else decays and dies, so the exact thing happens to our body.
This cycle of life, death, and rebirth is known as samsara. And this cycle is the one that sends our life energy to move from our physical body after death to another form.
However, as many religions happen to focus on living a real-life to live a better afterlife, so does the Buddhist. They believe that they will live a more robust hereafter through the proper actions, ethical conduct, the development of wisdom, and concentration. It is these actions of positivity that make it a reality for them to have a better rebirth. In the meantime, adverse effects lead to the opposite path.
Once the human has received true enlightenment, or Nirvana once the individual dies physically, they escape the cycle of samsara. To gain wisdom, the Buddhist must finally understand and accept the Four Noble Truths and become awakened to reality.
The same ideology, which is to both do and think positively to progress, is the exact ideology known as the belief of Karma. If you do the right actions for others and grow confidently, you will gather good Karma. Correctly, doing adverse reactions, and leading a negative life will gather bad Karma, and disturb your progression through rebirth.
Buddha taught his disciples not to be afraid of death, but instead to look forward to it as gaining another step towards enlightenment. Once an individual has died, Buddhists believe that they are reincarnated in one of 6 realms; heaven, hell, animals, human beings, Asura, or hungry ghost. Where the person goes, is decided by the Karma of the individual. However, these realms are not permanent.
And if anyone thought towards death was given by the Buddha, it was to prepare for death by purifying our mind, body, and spirit. He also explained that not becoming attached to material things is essential. So, rather than grabbing onto our temporary lives for dear life, he instead encouraged us to accept death as merely another step towards the ultimate goal, which is Nirvana.
