I'll have to get back with you on the books/vidoes.
It ws sooooo hard for me concentrate, read, watch a video I loiterally every day had to practice sitting quietly.......
Sitting Quitely was the hardest thing ever for me. Clearing my mind was even harder! Oh man, I always used to say if I lost my mijnd I wouldn't bother looking for it cause it was no dang good anyways! LOL......
I started by sitting quietly and a sweet lady from here who I haven't seen in a awhile told me a good, short meditation that is short...and was amazingly quite effective for me.
Light a candle, while looking into flame focus on breathing while saying I breathe in...I breathe out, only needs done 1 minute or so at a time............it sounded too simple to me, (I guess in my stinking thinkin complicated is 'better'.......go figure.)
Be patient with yourself, it takes time, but it DOES get better.
Warmest Hugs coming your way........
