The teachings of Bahá'u'lláh are the light of this age and the spirit of this century. Expound each of them at every gathering.
The first is investigation of truth,
The second, the oneness of mankind,
The third, universal peace,
The fourth, conformity between science and divine revelation,
The fifth, abandonment of racial, religious, worldly and political prejudices, prejudices which destroy the foundation of mankind.
The sixth is righteousness and justice,
The seventh, the betterment of morals and heavenly education,
The eighth, the equality of the two sexes,
The ninth, the diffusion of knowledge and education,
The tenth, economic questions, and so on and so forth.
Strive that souls may attain unto the light of guidance and hold fast unto the hem of Bahá'u'lláh. ('Abdu'l-Baha, Selections from the Writings of Abdu'l-Baha, p. 107)
