The Baha'i faith teaches that life after death is a continuation of the spiritual journey, in which the soul continues to progress and develop. According to Baha'i beliefs, the soul is a separate entity from the physical body and continues to exist after death.
Baha'is believe that the soul will experience a process of spiritual transformation after death, as it passes through a series of spiritual realms. The nature of these realms and the specific experiences of the soul in each realm are not fully understood or described in detail, but Baha'is believe that the soul will continue to learn, grow, and develop in these realms.
Death is a natural part of life. When a loved one passes onto the next world, we are reminded of how this fleeting world means nothing and how all our material possessions and worries are vain and irrelevant. Constantly remembering them in our daily prayers, undertaking charity work on their behalf and giving to the Bahá'í fund (for Bahá'ís only) on their name are just some things we can do while still on this Earth to help the souls of those that have departed progress in all the worlds of God.
This is a beautiful prayer from the Bahá'í Writings written by ‘Abdu’l-Bahá for the dead:
O my God! O Thou forgiver of sins, bestower of gifts, dispeller of afflictions! Verily, I beseech Thee to forgive the sins of such as have abandoned the physical garment and have ascended to the spiritual world.
O my Lord! Purify them from trespasses, dispel their sorrows, and change their darkness into light. Cause them to enter the garden of happiness, cleanse them with the most pure water, and grant them to behold Thy splendours on the loftiest mount.
