My cousin lost her life to cancer because of her limited knowledge & ‘not knowing’ about her illness and the options that she had to fight with it to save her life.
But, in the realm of ‘mindfulness’ & 'not knowing' versus ‘knowing’, I admire letting go of what we know (which is very hard) and allowing ‘not-knowing’ in order to give the opportunity to new thoughts, ideas, innovations, and looking at things differently. For example I’m looking at my son’s addiction problems differently lately because of letting go of what I know.
I guess Mindfulness as knowing & mindfulness as not-knowing complement each other and bring wholeness to our life.
Although it is sometimes better not to know than to know, in general, knowledge is power. By acquiring knowledge people equip their brains to make informed decisions about difficult and complicated questions. Informed decisions are the direct result of rational thinking, which encourages the development of logic and reason, which makes people excel at solving problems effectively.
Yes, knowing is almost always better than not knowing. If you are to live in ignorance then you give up the opportunity to determine your own fate. With knowledge comes power and the ability to control your destiny. For example, if someone wanted to remain ignorant about whether or not they have some deadly disease they give up the opportunity of potentially curing themselves if they are diseased.
Although knowing things might educate ones perspective, Being faced with the ugly truth uncovers the horrors of the world. Take The Giver for example, How can you not be in bliss not seeing what the giver does. You can't not, Its inevitable. When your a kid and all you want to be is a princess, You're dream is so real until you discover the truth that that will really never happen. And before that point that ignorance lead you to believe anything is possible. Although ignorance sometimes has a negative connotation sometimes simply being ignorant of something isn't your fault.
When you know less, you worry less. Why would people want to worry? That stresses people out! Everyone should be happy and if no one is happy then how is the world suppose to grow and become more intelligent? It's that simple. People don't need to know everything. More intelligent people aren't as happy as the less intelligent.
