Can you know your purva janma?

In many spiritual and philosophical traditions, particularly in Hinduism and Buddhism, the concept of "purva janma" refers to one's past lives. Some believe that through practices like meditation, regression therapy, or spiritual insight, individuals can gain awareness of their past incarnations. However, scientific evidence supporting the ability to recall past lives is lacking, and such experiences are often subjective. Ultimately, the understanding of purva janma varies widely among different cultures and belief systems.
