This quote suggests that our true nature is not confined to our physical bodies and temporal existence, but rather extends beyond into the realm of the infinite and spiritual. It implies that we are not just humans living a physical life, but spiritual beings who are currently experiencing life in human form.

The "infinite spiritual being" refers to the concept of the soul or spirit that is believed to be eternal in many spiritual and religious traditions. This part of us is not bound by time, space, or the physical laws that govern our human bodies. It is free, limitless, and connected to a greater cosmic consciousness or divine source.

The "temporary human experience" refers to our current life on earth, which is transient and finite. Our bodies age, our memories fade, and eventually, our lives end. However, if we see ourselves as spiritual beings, then death is not an end, but a transition, a change in form rather than a cessation of existence.

Applying this idea in today’s world or in personal development can have profound implications. It can change how we view ourselves and others, leading to greater empathy, compassion, and understanding. If we see ourselves as spiritual beings, we may strive to live in a way that nurtures our spirit and aligns with our higher purpose, rather than focusing solely on material or worldly success.

It can also change how we deal with challenges and hardships. If life is seen as a temporary human experience, then every challenge becomes an opportunity for spiritual growth and learning. Difficulties are no longer pointless suffering, but valuable lessons that help us evolve as spiritual beings.

Moreover, viewing ourselves as infinite spiritual beings can help alleviate the fear of death. If our true essence is eternal, then death is simply a transition, not an end. This perspective can bring comfort and peace in the face of mortality.

Finally, this idea encourages us to value and cherish our human experience. It’s a rare opportunity for the soul to learn, grow, and experience the physical world with all its beauty, complexity, and diversity. Therefore, every moment is precious and should be lived fully and mindfully.
