Bahá’í World Faith—Selected Writings of Bahá’u’lláh and ‘Abdu’l-Bahá (‘Abdu’l-Bahá’s Section Only)

I now assure thee, O servant of God, that, if thy mind become empty and pure from every mention and thought and thy heart attracted wholly to the Kingdom of God, forget all else besides God and come in communion with the Spirit of God, then the Holy Spirit will assist thee with a power which will enable thee to penetrate all things, and a Dazzling Spark which enlightens all sides, a Brilliant Flame in the zenith of the heavens, will teach thee that which thou dost not know of the facts of the universe and of the divine doctrine. Verily, I say unto thee, every soul which ariseth today to guide others to the path of safety and infuse in them the Spirit of Life, the Holy Spirit will inspire that soul with evidences, proofs and facts and the lights will shine upon it from the Kingdom of God. Do not forget what I have conveyed unto thee from the breath of the Spirit. Verily, it is the shining morning and the rosy dawn which will impart unto thee the lights, reveal the mysteries and make thee competent in science, and through it the pictures of the Supreme World will be printed in thy heart and the facts of the secrets of the Kingdom of God will shine before thee.
