If you are working on spiritual development, reading is a great deal better than meditation

And the right kinds of yoga are not the ones with the pants. Go clean cages at an animal shelter, if you want to do yoga. We call that bhakti yoga, working on your heart. Do something nice.

What you need to understand is that the goal is reached by grace, not by mechanical effort. You are working toward knowledge of God and of the celestial level, above the astral. Effort is necessary, but it comes by grace, it's not something you can do formulaically. 

Obviously it matters a great deal what you read, and you're better off with older stuff, and real physical books.
