It seems to me that the unconditioned dimension of a mind is a free mind. What has worked for me is noticing my present experience. I am helped every day when I say: "May I be generous and helpful. May I be virtuous. May I be patient. May I be able to bear and forbear the wrongs of others. May I be strenuous, energetic, and persevering. May I meditate and achieve concentration and oneness. May I be wise and use the wisdom for the benefit of everyone and everything." this is said not to a separate being as a reminder to myself that I am one with everyone and everything. As I notice that I am a whole which is more than the sum of the parts, at times, I begin to come near seeing myself not as one, but as "ONE". As Einstein said the true value of a human being can be found to the degree that that he gets rid of his separate self. Noticing yourself as the ocean full of drops and waves can help you see that you are more than one drop or one wave. As you notice you are more ONE, you also notice there is no separate one to have desires. When you have desires you are not free. Desires are a condition that keeps one from being unconditioned. Thank you for the opportunity to respond. Warm and kind regards to everyone.
