What is the first level of heaven?

Will Insight tell us, which heaven he is in? 

In the very first sphere above the spiritual heaven. The celestial heaven in its highest state is still very far above me. I am and have been since you first came to me in this sphere of the celestial heavens. Did you think otherwise? I have told you many times that the spheres or states here are without number. You ask the same thing over and over again, but that is right—come to me always with the thought and wish of your heart, for a teacher must expect to repeat himself many times, but learn patience with those who come to you in the same way, forgetting what you have given them.
