The Master said guidance was when the doors opened after we tried. We can pray, ask to do God's will only, try hard, and then if we find our plan is not working out, assume it is not the right one, at least for the moment.
It is not sufficient to pray diligently for guidance, but this prayer must be followed by meditation as to the best methods of action and then action itself. Even if the action should not immediately produce results, or perhaps not be entirely correct, that does not make so much difference, because prayers can only be answered through action and if someone's action is wrong, God can use that method of showing the pathway which is right.
In this journey the seeker becometh witness to a myriad changes and transformations, confluences and divergences. He beholdeth the wonders of Divinity in the mysteries of creation and discovereth the paths of guidance and the ways of His Lord. Such is the station reached by them that search after God, and such are the heights attained by those who hasten unto Him.
O My Friends! Quench ye the lamp of error, and kindle within your hearts the everlasting torch of divine guidance. For ere long the assayers of mankind shall, in the holy presence of the Adored, accept naught but purest virtue and deeds of stainless holiness.
Know thou of a truth that the seeker must, at the beginning of his quest for God, enter the Garden of Search. In this journey it behoveth the wayfarer to detach himself from all save God, and to close his eyes to all that is in the heavens and on the earth. There must not linger in his heart either the hate or the love of any soul, to the extent that they would hinder him from attaining the habitation of the celestial Beauty. He must sanctify his soul from the veils of glory and refrain from boasting of such worldly vanities, outward knowledge, or other gifts as God may have bestowed upon him. He must search after truth to the utmost of his ability and exertion, that God may guide him in the paths of His favour and the ways of His mercy. For He, verily, is the best of helpers unto His servants. He saith, and He verily speaketh the truth: "Whoso maketh the efforts for Us, in Our ways shall We assuredly guide him." And furthermore: "Fear God and God will give you knowledge."
