If not, spend more time in the visualization process. The importance of the goal, dictates the ease with which you are able to purify your intention. If your goal is really near and dear to your heart, and you haven't accomplished it, you've probably developed some negative beliefs about your ability to achieve it. When your vision for your goal and your belief in accomplishing it become congruent, you're on your way. I am enough of an artist to draw freely upon my imagination.
Imagination is more important than knowledge.
Knowledge is limited. Imagination encircles the world. If you want radishes, then sow radish seeds. If you want love, money, friendship, peace, success, happiness, health, wealth, wisdom, or anything else, you must also sow the correct seeds. Remember, you are currently reaping the bounty of what you planted in the past.
