I've heard and read ...that INTENTION is one of the key factors. That you need to intend to accomplish whatever you wish to do. I would like for whoever is knolegable in this to go in depth into what exactly intention is and how it is properly utilized.

You got some good answers already . I would like to add that intention becomes more powerful as the magician develops the energy body and raises the vibration . Franz Bardon writes about joining will , focus and visualisation with intention in order to manifest . Doing these together in meditative trance is most effective .
Sit in dim light in a throne position
Open in protection
Deep Cleanse Breathe Crown to Toes
Raise Energy Toes to Crown
Close the physical eyes
enter meditative trance
focus on the now
visualise the perfect outcome
will this to manifest and send energy from the brow centre into the visualisation
focus and intend this to come to you
do not ask or want say instead thank you for having it now
