Here is what you need:
A computer. I am going to assume you have one if you're reading my blog.
Internet access. See above.
This is how you do it:
Go to the Apple website and download iTunes. From the main site, click on "Downloads" in the top menu bar to go to the download page. On the left side of the page, under "Top Downloads", is iTunes. It's free to download and easy to install.
Once you have installed iTunes, go into the program and click on "iTunes Store" in the left frame. You will then be taken to the iTunes store where there is a plethora of stuff to peruse! However, most of it costs money. So be careful what you download!
On the left side of the store window, click on podcasts. Then you will be taken to all the podcasts available through iTunes. And THESE are free, so take what you need! To find specific podcasts on Fibromyalgia or meditation, or whatever you're looking for, click on "Power Search" on the right side of the iTunes store window. Type your search keywords in the "Description" text box and hit enter.
If you find a specific podcast that you like, and is still active, subscribe to it! You can always delete them later after you've listened.
Each podcast show will list their podcasts at the bottom of the iTunes store window. To download, you may have to use the scroll bar at the bottom to scroll the frame to the left and access the buttons on the right.
To listen to your podcasts, simply click on "Podcasts" in the iTunes window (outside the frame in which the store is being shown). Your podcasts will be grouped by the name of the show and clicking on the arrow before the name will allow you to expand or collapse the list of podcasts. If a podcast episode is grayed out, you don't have it. But you can get it by simply clicking on the button to the right of episode name.
There is so much information available to us through podcasts, it just takes a little searching. Once you have what you need, you can just relax and listen to the podcast from your computer or save it to a CD and listen to it wherever you are.
Gentle hugs and happy podcast hunting!
