SOLOMON, the Son of David, King of Israel, hath said that the beginning of our Key is to fear God, to adore Him, to honour Him with contrition of heart, to invoke Him 1 in all matters which we wish to undertake, and to operate with very great devotion, for thus God will lead us in the right way. When, therefore, thou shalt wish to acquire the knowledge of Magical Arts and Sciences, it is necessary to have prepared the order of hours and of days, and of the position of the Moon, without the operation of which thou canst effect nothing; but if thou observest them with diligence thou mayest easily and thoroughly arrive at the effect and end which thou desirest to attain.
10:1 1202 Lansdowne MSS. omits the concluding part of this sentence.
