Answer: The concept of self-love contributes to the idea that someone has to love themselves before they love others. Self-love has a lot of reflection on your personality and self-esteem. Human nature needs self-love in order to live a happy and fulfilling life full of acceptance. The quote "All is self-love" refers to personality to who you truly are, so when you show and express your true colors, it's all self-love.
