There are plenty of verses that suggest that photoreading isn't Satanic...
1 Corinthians 6:12 "Everything is permissable for me, but not everything is beneficial." ->Is photoreading beneficial to you? Would God be pleased if you photoread the Bible?
1 Cor 10:26 "For the earth is the Lord's and everything in it." ->God created your mind and subconscious mind both, use them BOTH to glorify Him.
1 Cor 10:31 "So whether you eat or drink or whatever you do, do it all to the glory of God." -> So long as in whatever you do you glorify God it doesn't matter so much what you do. Are you intentionally relaxing your mind to give Satan a threshold? Or to learn more and be a knowledgable Christian?
Romans 13:10 "Love does no harm to it's neighbor, therefore love is the fulfillment of the law." -> Is photoreading a hateful thing to do?
John 3:18 (Jesus speaking) "Whoever believes in Him is not condemned, but whoever does not believe stands condemned already because he has not believed in the name of God's one and only Son." -> If you believe in Christ Jesus, then you are good already. That doesn't mean you should go become a Satanist, but since you are saved, try to glorify Him through whatever you do now. When you photoread, photoread commentaries and stuff so that you are more knowledgable about what God's Word says.
