In Nichiren Buddhism, the concept of rebirth is viewed as a continuous cycle of life and death, also known as samsara. This cycle is seen as a result of our past actions and karma, which determines our future existence. However, unlike other Buddhist traditions, Nichiren Buddhism places a strong emphasis on the importance of the present life and how we can achieve liberation in this lifetime.

According to Nichiren Buddhism, the ultimate goal is to attain enlightenment and break free from the cycle of rebirth. This is achieved by having faith in the Lotus Sutra, which is considered to be the ultimate teaching of the Buddha. The Lotus Sutra teaches that all beings have the potential to attain enlightenment and that this can be achieved in one's current lifetime.

Nichiren Buddhism also teaches that the concept of rebirth is not limited to physical existence, but also includes the rebirth of our thoughts, emotions, and actions. Therefore, it is important for practitioners to constantly strive to purify their minds and cultivate positive thoughts and actions in order to break free from the cycle of suffering.

In Nichiren Buddhism, the concept of rebirth is also closely tied to the law of cause and effect, or karma. It is believed that our actions in this lifetime will have an impact on our future existence. By chanting the mantra "Nam-myoho-renge-kyo" and practicing the teachings of the Lotus Sutra, one can create positive karma and ultimately break free from the cycle of rebirth.

Additionally, Nichiren Buddhism teaches that each individual has their own unique path to enlightenment and that everyone's journey is different. Therefore, it is important for practitioners to have faith in their own potential and to constantly strive towards self-improvement and enlightenment.

In conclusion, Nichiren Buddhism views the concept of rebirth as a continuous cycle of life and death, influenced by our past actions and karma. However, through faith in the Lotus Sutra and the practice of chanting and self-improvement, one can attain enlightenment and break free from this cycle in their current lifetime.
