The spiritual nature of teaching, qualities and attitudes, and the act of teaching are the main themes explored in Teaching the Cause. The capacities built include that of teaching the Faith through individual initiative and as part of collective teaching campaigns.

Bahá'ís everywhere are engaged in a global process of learning that is helping to build their capacity to apply the teachings of Bahá'u'lláh to the transformation of society. As a contribution to this learning process, the Ruhi Institute carries out action and research in the field, in order to develop programs and materials that enhance the capacity of individuals and communities to serve humanity.

The main sequence of courses is organized so as to set the individual, whether Baha'i or not, on a path being defined by the accumulating experience of the community in its endeavour to open before humanity the vision of Baha'u'llah's World Order.

The very notion of a path is, itself, indicative of the nature and purpose of the courses, for a path invites participation, it beckons to new horizons, it demands effort and movement, it accommodates different paces and strides, it is structured and defined. A path can be experienced and known, not only by one or two but by scores upon scores; it belongs to the community. To walk a path is a concept equally expressive. It requires of the individual volition and choice; it calls for a set of skills and abilities but also elicits certain qualities and attitudes; it necessitates a logical progression but admits, when needed, related lines of exploration; it may seem easy at the outset but becomes more challenging further along. And crucially, one walks the path in the company of others.
