Summoned Beings Appear But Do Not Listen. Options

I have worked about 5 evokations. I am clearly not an expert. The last time that I summoned a being it appeared in my triangle. 'visibly' for a few moments. I cannot understand why these beings do not listen to me. I will admit that I did not go into details of controling the being ect... such as in the goetia. Perhaps it is these simple details; or that my mind may prevent the intervention do to a lack of understanding of the beings purpose. What is their motivation. Also they appear and do not act... So perhaps I am growing a slight mental illness. However they have worked in the past but recently it has not.

Much the same as in spell work. Is it common to experience ups and downs that come in time and with understanding; or am i just not tapping into myself correctly.

Other than the double posting I have to agree w/ that last post--sort of (sort of being I never used Goetic callings but use 50 Names of MARDUK callings ). I dont use circles either. It is insulting to these spirits. You are saying u r afraid of them and want to hide behind a shield and boss them around. They dont take too kindly to that attitude. They respect a sense of bravery when dealing w/ them. If you show them respect they will communicate w/ u much easier and more friendly like. And to use their powers is to ask for assistance and to recognize them for their assistance is not a bad idea as well. Arrogance wont get you very far in these type of workings.
