In a world that seems to have lost all sense of direction, one glimmer of hope is the gradual emergence of the Bahá'í Faith as a rational alternative to the bankrupt philosophies and failing economic systems to which much of the world is still clinging. It represents a beautiful balance of the material and the spiritual, the East and the West, the vigor of youth and the wisdom that comes with age, science and religion, male and female, mystical and rational.
Whatever I have done in life, the Bahá'í teachings have inspired, guided and confirmed my choices. There has never been any separation between my work as a scientist and my beliefs as a Bahá'í; on the contrary they have formed an integrated whole. I could never have accomplished what little I have been able to do for governments, the United Nations system, and various non-governmental organizations without the inspiration of the Bahá'í teachings, the understanding and reinforcement that comes from Bahá'í community life, and the remarkable people with whom I have collaborated over the years. In every country that I have visited, I have found among the Bahá'ís the same sense of belonging to one human family, regardless of culture, economic or social status.
As the Universal House of Justice, the international governing body of the Bahá'í Faith has put it: “… these are communities that define themselves by their commitment to the oneness of humanity. They value the rich diversity represented by all the world’s kindreds, while maintaining that one’s identity as a member of the human race has precedence before other identities and associations. They affirm the need for a global consciousness, arising from a shared concern for the well-being of humankind, and they count all the peoples of the earth as spiritual brothers and sisters. Not content with simply belonging to such communities, Bahá’u’lláh’s followers are making constant effort to invite like-minded souls to join them in learning how to put His teachings into effect.”
I can only recommend to all who come across this page to investigate the teachings of Bahá'u'lláh, the Prophet-founder of the Bahá'í Faith. While the path these teachings lay out is not an easy one, there is no better way to fulfil your human potential and to live a life of productive service. The web sites below provide extensive information on the Bahá'í Faith. Also, since it is the second most widespread of the world's religions, you are almost certain to find a Bahá'í community near you.

Since the Bahá'í Faith has no clergy or priesthood, activities in local and national communities are organized by the Bahá'ís themselves, usually with the guidance of their elected institutions. The community-building process includes devotional gatherings, study circles, children's classes, and activities for junior youth (pre-adolescents), open to everyone in the community, not just the Bahá'ís. The materials used in this Institute process have been developed over many years by the Ruhi Institute in Colombia, and have proven their effectiveness around the world in many cultural contexts. Their purpose is to build the capacity of everyone to participate in processes of spiritual and social transformation. At the core is a sequence of "Ruhi Books" used in local study circles guided by a tutor, where short quotations from the Bahá'í writings and guidance provide the basis for deep reflection and inspire acts of service.
The main sequence of courses, for those 15 or older, include:
• Book 1 - Reflections on the Life of the Spirit
• Book 2 - Arising to Serve
• Book 3 - Teaching Children’s Classes
• Book 4 - The Twin Manifestations
• Book 5 - Releasing the Powers of Junior Youth
• Book 6 - Teaching the Cause
• Book 7 - Walking Together on a Path of Service
Completing this sequence provides the essentials one needs to find one's own path of service and to help others to do the same. Beyond this sequence, other books are being developed to go more deeply into different aspects of Bahá'í community life and service.
If you are interested, contact your nearest Bahá'í or Bahá'í community.

Growing out of childhood raises many questions about our human purpose, discovering our spiritual nature, and learning to use prayer for our spiritual growth. In a world with so many crises and threats, anxiety is a real problem. Dan Jordan many years ago wrote an article on becoming your true self, from which we have extracted some useful guidance for young people. Learning to use prayer effectively is one way to grow through these problems.

The Nine Year Plan 2022-2031 is the present framework for Bahá'í community activities. Young people need to understand where they fit within the plan and how it can help them to set their own priorities and find their best paths to be of service. Community building through the Institute process, teaching, social action and public discourse are major dimensions of the plan. Further lessons develop the environment as an example of public discourse, from exploring relevant Bahá'í principles to finding receptive audiences, including the example of the Bahá'í International Community.

These seven classes with more simplified language for older children and junior youth are available both with my pictures of the beauties of nature (large files) and as text alone where size is a problem, in both pdf formats readable online and as powerpoint presentations for downloading.

The Universal House of Justice, the international governing body of the Bahá'í Faith, issued the statement "The Promise of World Peace" in 1985 as a call to world leaders and the peoples of the world to bring an end to war and conflict and to apply the Bahá'í teachings on unity and collective security to achieve world peace. These five classes present a simplified version of the text suitable for older children and youth who worry about war, to help them see that peace is possible and how to get there.

In 1995, for the United Nations Social Summit, the Bahá'í International Community's Office of Public Information issued a beautiful statement "The Prosperity of Humankind" to explain how Bahá'í principles provided a whole new way to look at issues of social and economic development. It showed the importance of the oneness of humankind, justice, redefining human relationships, access to knowledge, science and religion, economic issues, power and authority, and reshaping institutions. These eight classes with a simplified text can help older children and junior youth to acquire a Bahá'í approach to social and economic development in order to eliminate poverty.
