Know youself is one of the statements at the temple of Delphi, which has been influencing the Greek philosophers and therefore the thinking of Europe as a whole.
If you say “I don´t want to say ABC, but … “, you already said ABC. Same is true for your consciousness and all your life. The negation does not exist in terms of your consciousness. The expansion and compassion of your consciousness lies in the positivity of the negations. Know yourself and have compassion with yourself.
That basically means, that you are also everything that you are not. Most of that is unconscious or hold with negative emotions and thoughts and with consciousness and compassion you can turn them into positivity.
