That there must be full integration of the aging in the human community, since the community should be an extended family in which everyone, of any age, is an essential part, and not only allowed, but encouraged, to make the fullest possible contribution to the wellbeing of the whole; and that in considering the needs of the aging in the process of development we must take into account the wholeness of the human being—the moral and spiritual dimension, besides his emotional, intellectual, and physical nature—when discussing the special contributions of older persons to development and their sharing in the resulting benefits.
(Bahá’í International Community to the first UN World Assembly on Ageing, 1982, Bahá’í World, Volume 18, p. 397)
The whole physical creation is perishable. These material bodies are composed of atoms; when these atoms begin to separate decomposition sets in, then comes what we call death. This composition of atoms, which constitutes the body or mortal element of any created being, is temporary. When the power of attraction, which holds these atoms together, is withdrawn, the body, as such, ceases to exist. With the soul it is different. The soul is not a combination of elements, it is not composed of many atoms, it is of one indivisible substance and therefore eternal. It is entirely out of the order of the physical creation; it is immortal!
(‘Abdu’l-Bahá, Paris Talks, p. 90-91)
