To attain eternal happiness one must suffer. He who has reached the state of self-sacrifice has true joy. Temporal joy will vanish.
Abdu'l-BaháAnd now one of the greatest and most fundamental principles of the Cause of God is to shun and avoid entirely the Covenant-breakers, for they will utterly destroy the Cause of God, exterminate His Law and render of no account all efforts exerted in the past.
Abdu'l-BaháThe spirit does not need a body, but the body needs spirit, or it cannot live. The soul can live without a body, but the body without a soul dies
Abdu'l-BaháOne must see in every human being only that which is worthy of praise. When this is done, one can be a friend to the whole human race. If, however, we look at people from the standpoint of their faults, then being a friend to them is a formidable task............ .....Thus is it incumbent upon us, when we direct our gaze toward other people, to see where they excel, not where they fail.
Abdu'l-BaháIn every aspect of life, purity and holiness, cleanliness and refinement, exalt the human condition . . . Even in the physical realm, cleanliness will conduce to spirituality.
Abdu'l-BaháObserve 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-Bahá
