Personally, I like to think of No This way because I had a really tough time saying No, Let's say a child is doing something that will hurt themselves or is unsafe your first reaction is to tell them No to stop them from doing what they are doing not because you hate them or you don't love them but because you do love them and care for them.
You have to think of yourself in those terms you love and honor yourself enough not to put yourself in a situation that would hurt you physically, emotionally, and mentally. We often times do because we fear that the word No will get us rejected and it might.
You have to remember that rejection is the divine protection and the divine is your parent and only wants what is best for you and will do all in its power to help you if you allow it.
