Pick a week in a month and on that week, you cannot lie. When people ask you for your opinions, try your best not to lie. Even if you experience the fear of hurting other people's feelings, or the fear of being rejected by other people, and whatever situation you earn, and this no mind week, just speak the truth. No doubt you will encounter situations which will bring out the fear and imagination of what could happen if you speak the truth. These are the situations that you need to face with honesty for you to develop greater self transformation. If you experience fear, great, if you experience negativity, right, this is the process of uncovering the hidden negativities within.
Always practice with intention to develop self acceptance, to accept yourself for who you are, and to accept others for who they are. Even if they end up rejecting you through the process, you will develop great self acceptance. And when you find yourself in situations of experiencing negative ideas, such as it is not okay to be honest. Just tell yourself that it's okay to be honest. And this will help to greatly drive you to be even more honest. Going through these experiences of being honest with yourself, will greatly transform your mind.
