How can I change my perception to overcome reification?

Reification is a way of conceptualization or objectification or mental modeling through which we form ideas, beliefs, and make an understanding of our surroundings. However, I saw a youtube video which explains that we have to overcome reification and/or social conditioning for spiritual enlightenment. But, the video does not explain the 'how'. So, my question is, how can we change/work-on **our perception** of the surrounding/ environment/society/beliefs, etc so that we see things as they are, like '***yathabhutam***'?
