Absolutely not! Though there are types of vessels and bindings out there that trap, harm and imprison demons and spiritual entities we DO NOT bind in this way.  There are many archaic and old traditions which call for forced bindings and imprisonment of demons, this is against out path and against everything we stand for.  We work with demons from a place of respect and adoration.  We are completely against forceful or restrictive bindings in any way and will not subject any of our entities to these cruel and archaic practises.
So then what do we actually do.  Our bindings we call flexible bindings because they do not harm or imprison the demon in any way.  The bindings link the demons energies to the physical vessel which is created using energies of the Vessel.  This link creates a physical focus point that creates a sacred space for communication and connection.
The demon is in no way trapped to the vessel and can actually move around at will.  They are not bound to their vessel and you will not need to have your vessel on you to communicate and connect with you demon though the focused energies of the binding and the vessel make communication easier in the beginning and give the demon a physical focal point to manipulate the world around them.
They are completely free to do as they desire and in the event of abuse from a human companion, the demon has full control to break their bindings and end the connection.  We want to ensure that any demon we bring through is not bound or harmed in any way.  We respect and care for the demons we conjure and any abuse on them will not be tolerated.
They are not forcibly bound in any way and they have full control over what happens to them.  They have chosen to come through here and walk with human companions in an empowered way.  They are dark gods and they deserve to be treated with respect.  We approach them as friends, guides and mentors.. NOT as slaves.
