That which gives the impression that ‘I am machine’ is the belief in matter, the belief in a physical reality.
Believing that there is a reality called matter, leads to the impression of physicality and has yet to be established by scientist who are looking for ‘matter’.

When the body is perceived as a physical reality and not just as a manifestation/modulation of consciousness, the sense of separation gets established.
The belief and feeling that I am a physical form born in time and space is unhappy…. machine like, so to speak.

Without the contemplation of truth, this impression of being a physical form born and existing in time and space is maintained through infinite kalpas.
Only awakening and the realization of Self dissolves these karmic realms.
