Many of us have desires that, when un-manifested, leave us feeling frustrated and unfulfilled. These are usually the deeper heart / soul desires like finding our life's purpose, how we can best serve or finding our "soul mate" / soul group.
Energy flows in the direction of our thoughts and feelings. Setting an intention is paramount. There is an emotional component required as well as the unwavering knowledge that the manifestation is already complete. By feeling it, touching it, seeing it, acting 'as if', we make it so.
Sometimes we just need to trust in the cosmic process.
As one goes into mastery levels, life becomes more synchronistic. Physical manifestations can become nearly instantaneous and effortless. One learns to trust in divine timing and the perfection of all things.
