In the beginning of his human life man was embryonic in the world of the matrix. There he received capacity and endowment for the reality of human existence. The forces and powers necessary for this world were bestowed upon him in that limited condition. In this world he needed eyes; he received them potentially in the other. He needed ears; he obtained them there in readiness and preparation for his new existence. The powers requisite in this world were conferred upon him in the world of the matrix.
Abdu'l-BaháStrive with all your hearts, raise up your voices and shout, until this dark world be filled with light.
Abdu'l-BaháThe human spirit may be likened to the bounty of the sun shining on a mirror. The body of man, ... grows and develops through the animal spirit.
Abdu'l-BaháBe not the slave of your moods, but their master. But if you are so angry, so depressed and so sore that your spirit cannot find deliverance and peace even in prayer, then quickly go and give some pleasure to someone lowly or sorrowful, or to a guilty or innocent sufferer! Sacrifice yourself, your talent, your time, your rest to another, to one who has to bear a heavier load than you - and your unhappy mood will dissolve into a blessed, contented submission to God.
Abdu'l-Bahá
