The pure heart is one that is entirely cut away from self. To be selfless is to be pure.
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-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-BaháTo oppose knowledge is ignorant, and he who detests knowledge and science is not a man, but rather an animal without intelligence. For knowledge is light, life, felicity, perfection, beauty and the means of approaching the Threshold of Unity. It is the honor and glory of the world of humanity, and the greatest bounty of God. Knowledge is identical with guidance, and ignorance is real error
