In order to receive, we must first empty. There are so many ways to do this important first step.
Clearing your chakras( a million ways to do this.), grounding, breathing, toning, stretching.
Letting go of your day, getting out the kinks, clearing your mind, releasing all the gunk we have picked up from others and the gunk we make ourselves.
Purification, if you will. It is not hard and fun really to see all the stuff go flying off your aura. It is like exercise, which clears toxins and tension, afterward leaving you so relaxed.
The first section of most of the meditations are clearing and relaxation so we can be open enough to go where our souls are leading us.
For an example of one type of clearing, go to http://meditatewithfriends.com the products page and click on free sample. (After that is a free meditation for students, which anyone could use, really)
I also often clear my chakras at night as I am falling asleep, or even in the middle of the night, and then send prayers and healing to those I think of.
All of this comes down to working on yourself, becoming more conscious of where your body and mind are, and making room for your Higher Self to show up.
