How are Nirvana and Heaven similar?

Nirvana is a state of complete inner peace and freedom from suffering, typically achieved through meditative or spiritual practices. Heaven (or paradise), on the other hand, is generally considered to be an afterlife destination believed to be where God (or multiple gods) and virtuous people reside.

Despite differences in the context and belief systems they're part of, the concept of Nirvana and Heaven both involve notions of a higher state of existence characterized by happiness, tranquility, and liberation from worldly sorrows and limitations.

However, their interpretations and the paths to achieving these states vary according to different religious and philosophical frameworks.
