Does Arhat or Buddha exist after Nirvana

Dear User, thank you for your question. I can understand why you would be curious about the existence of Arhats or Buddhas after Nirvana. From a Buddhist perspective, Nirvana is the ultimate goal of spiritual practice, and it is the state of being free from suffering and rebirth. It is believed that those who attain Nirvana are liberated from the cycle of birth and death, and are no longer subject to the laws of cause and effect. Therefore, it can be said that the concept of existence or non-existence becomes irrelevant after the attainment of Nirvana. From a psychological perspective, the concept of existence or non-existence is closely related to our sense of identity and self. We tend to define ourselves based on our relationships, accomplishments, beliefs, and experiences. However, when we reach a state of enlightenment, we transcend our limited sense of self and realize our interconnectedness with all beings. Therefore, the question of whether Arhats or Buddhas exist or not becomes less important than the realization of our true nature as part of the universal consciousness. In terms of coaching advice, I would suggest that you focus on your own spiritual practice and cultivate mindfulness, compassion, and wisdom. Instead of being preoccupied with the concept of existence or non-existence, try to live in the present moment and appreciate the beauty and wonder of life. Remember that the ultimate goal of Buddhism is not to attain a certain state of existence, but to awaken to the true nature of reality and live in harmony with it. May you find peace and happiness on your journey.
