Love is a light
Be ye sincerely kind, not in appearance only. Let each one of God’s loved ones centre his attention on this: to be the Lord’s mercy to man; to be the Lord’s grace. Let him do some good to every person whose path he crosseth, and be of some benefit to him. Let him improve the character of each and all, and reorient the minds of men. In this way, the light of divine guidance will shine forth, and the blessings of God will cradle all mankind: for love is light, no matter in what abode it dwelleth; and hate is darkness, no matter where it may make its nest. O friends of God! That the hidden Mystery may stand revealed, and the secret essence of all things may be disclosed, strive ye to banish that darkness for ever and ever.
– Abdu’l-Baha, Selections from the Writings of Abdu’l-Baha
Yet, by the Living God, were there any true seeker, I would divulge it to him; for they have said: “Love is a light that never dwelleth in a heart possessed by fear.”
Verily, the wayfarer who journeyeth unto God, unto the Crimson Pillar in the snow-white path, will never reach unto his heavenly goal unless he abandoneth all that men possess: “And if he feareth not God, God will make him to fear all things; whereas all things fear him who feareth God.”
– Baha’u’llah, The Four Valleys, p. 58
Thou art God’s shadow on earth. Strive, therefore, to act in such a manner as befitteth so eminent, so august a station. If thou dost depart from following the things We have caused to descend upon thee and taught thee, thou wilt, assuredly, be derogating from that great and priceless honour. Return, then, and cleave wholly unto God, and cleanse thine heart from the world and all its vanities, and suffer not the love of any stranger to enter and dwell therein. Not until thou dost purify thine heart from every trace of such love can the brightness of the light of God shed its radiance upon it, for to none hath God given more than one heart. This, verily, hath been decreed and written down in His ancient Book. And as the human heart, as fashioned by God, is one and undivided, it behoveth thee to take heed that its affections be, also, one and undivided. Cleave thou, therefore, with the whole affection of thine heart, unto His love, and withdraw it from the love of anyone besides Him, that He may aid thee to immerse thyself in the ocean of His unity, and enable thee to become a true upholder of His oneness. God is My witness. My sole purpose in revealing to thee these words is to sanctify thee from the transitory things of the earth, and aid thee to enter the realm of everlasting glory, that thou mayest, by the leave of God, be of them that abide and rule therein.
– Baha’u’llah, The Summons of the Lord of Hosts, p. 214
