Dada Bhagwan said this quote

The Gnani Purush simply makes the separation in one’s vision: ‘This is the vision of the Soul, the real Self’ and ‘this is the vision of the worldly self’. Otherwise a person can never make this change in his vision. One’s vision of ‘I am Chandubhai’ (vikalpi drashti) will never become the vision of ‘I am the Pure Soul’ (nirvikalpi drashti).
