Apparently your reading skills taint your response.
Excuse me, but a bond is not 'chains'.
We are indeed bonded to flesh, so much so in fact, that the spirit became flesh. Your problem is that you still see them as two, when, in fact, they are one and the same. The form that the spirit is currently manifesting is temporal, just as the wave form which the sea manifests is temporal. Just as the wave form is made of the same substance as the sea, you too are made of the same substance as the Source from which you originally emerged and are now emerging, as living flesh, as we speak. When you 'die', your flesh form is broken down and transformed by other living things, such as macrophages and other bacteria, just as the ocean wave form dissolves back into the sea. Nothing is lost. Nothing dies.
You can no more escape the flesh any more than the eye can see itself. Stop grasping, and just allow the Self to settle upon itself.
You insult the divine nature that 'breathed' its life into your form by thinking yourself as 'chained', and desiring to escape. You are not living your life in joy, enjoying the Gifts of the Incarnation. As the Buddhist master said:
"You have one eye on the path and one eye on the goal, instead of both eyes on the path".
You are preoccupied with what you are going to 'get' as Reward in the so-called 'afterlife', like a child intent on what he is going to get for Christmas, and not paying attention to the reality right under your very nose.
If you are not here, now, you won't be there, then, and if you cannot be here, now, you may as well spend eternity in some forgotten grave as terrified dust. As TS Elliot said:
"I should have been a pair of ragged claws, scuttling across the floors of silent seas"
