In Nichiren Buddhism, the concept of enlightenment is viewed as the ultimate goal and purpose of our existence. It is the state of complete awakening and understanding of the true nature of life and the universe.

Unlike other forms of Buddhism, Nichiren Buddhism does not see enlightenment as something that can only be achieved after many lifetimes of practice and reincarnation. Instead, it emphasizes that enlightenment is attainable in this lifetime, through faith in the Lotus Sutra.

Nichiren Buddhism teaches that the Lotus Sutra is the highest and most complete teaching of the Buddha, containing all the essential teachings and methods for attaining enlightenment. It is believed that by chanting the mantra "Nam-myoho-renge-kyo" and reciting the Lotus Sutra, one can awaken their inherent Buddha nature and achieve enlightenment in this lifetime.

This concept of enlightenment is also closely tied to the idea of "attaining Buddhahood in this lifetime." In Nichiren Buddhism, it is believed that every individual has the potential to become a Buddha, and through faith in the Lotus Sutra, one can awaken this potential and realize their own Buddhahood.

Furthermore, Nichiren Buddhism emphasizes the importance of taking action in the present moment to create positive change and bring about enlightenment. This is known as "actualizing the Buddha's teachings," and it involves actively spreading the teachings of the Lotus Sutra and working towards creating a more peaceful and harmonious world.

In Nichiren Buddhism, enlightenment is not seen as a static state, but rather as an ongoing process of growth and development. It is believed that even after attaining enlightenment, one must continue to deepen their understanding and practice in order to fully manifest their Buddha nature.

Overall, Nichiren Buddhism views enlightenment as a realistic and achievable goal in this lifetime, through faith in the Lotus Sutra and active engagement with the teachings. It is a continuous journey towards awakening, self-discovery, and ultimately, liberation from suffering.
