I am the first to admit:
I might have a darker side.
I might be a vampire. Yea, I vamp others in order to fulfil my hidden desires.
I might act as a manipulator. I unconsciously manipulate others in other to feel some fulfilment of my hidden needs.
I might act as an abuser. I have acted as an abuser before because I needed to satisfy desires seeking others approval disregarding their will.
I might been a liar to achieve easily what I honestly could achieve.
I sometimes use the easiest way to achieve what I want. No worthy here.
The first step is to recognise the thoughts holding the darker self. This way there is space, room and conscious intelligence to change! And the power lies on change.
