Do not allow any clinging to any physical form, not even your own self or your Guru. Then you are left alone with Freedom and this will not be a glimpse, it will be a permanent abiding in your own Self.
You do not have to depend on anything to be Free and it is not a glimpse! Freedom is always permanently residing in your Heart so don't get rid of all these aids which give a glimpse of bliss. Don't depend on anything and simply keep Quiet. Let your mind not cling to anything of the past and check its futurizing tendencies.
