Observe that the body of man is confined to a small place; it covers only two spans of earth. But the spirit and mind of man travel to all countries and regions - even through the limitless space of the heavens - surround all that exists, and make discoveries in the exalted spheres and infinite distances. This is because the spirit has no place; it is placeless; and for the spirit the earth and the heaven are as one since it makes discoveries in both.
Abdu'l-BaháMan is in reality a spiritual being and only when he lives in the spirit is he truly happy.
Abdu'l-BaháWhatever other children learn in a year, let Bahá’í children learn in a month. The heart of ‘Abdu’l-Bahá longeth, in its love, to find that Bahá’í young people, each and all, are known throughout the world for their intellectual attainments. There is no question but that they will exert all their efforts, their energies, their sense of pride, to acquire the sciences and arts.
Abdu'l-BaháTo promote knowledge is thus an inescapable duty imposed on every one of the friends of God.
Abdu'l-BaháWe declare that love is the cause of the existence of all phenomena and that the absence of love is the cause of disintegration or non-existence.
Abdu'l-BaháMay you become as the waves of one sea, stars of the same heaven, fruits adorning the same tree, roses of one garden in order that through you the oneness of humanity may establish its temple in the world of mankind, for you are the ones who are called to uplift the cause of unity among the nations of the earth.
Abdu'l-Bahá
