Whenever I feel stuck in my practise I remind myself that the way out is straight through the stuckness.
Persist , read all available information, talk with people interested in the topic, ' pray '.
Keep up the practise , but also open up to new ways of seeing , feeling stuck is often a sign of growth, you have become too big for your current world view or understanding , the stuck feeling is often a sort of growing pain , something wants to burst through to conscious awareness. It is there just under the surface making you very uncomfortable unable to settle, this is good , this is life force that wants to be listened to and investigated.
This is the time to immerse in study and practise , a time to keep persisting and a shift will happen the doors of perception will open a little wider.
Inspiration will come the prayers will be answered in the form of books , articles , conversations or just insights that arise in silent reflections. So persist and growth is guaranteed.
