In order to understand spiritual intelligence it is useful to first be clear on what we mean when we use these two words.
To be ‘spiritual’ is to think, act and interact from an awareness of self as spirit not form, soul not body. Most of us are taught to believe we are our physical forms, and so we identify with our body or the labels we give to our bodies such as nationality, race, gender, profession etc. This wrong sense of self is what creates all fear, anger and sadness in life. From a spiritual point of view these emotions are always the result of ego (misidentification), which then blocks access to your true spiritual nature which is peaceful, loving and joyful.
Intelligence is to use what you know in the right way at the right time in the right place with the right intention. For example if you ‘know’ your self as a spiritual being you will also ‘know’ that you do not own or possess anything. When something in your life is damaged or lost, it does not affect you in any way – you are able to use your spiritual power to accept and move on. If someone praises the clothes you wear, or insults you in any way or comments negatively about your looks, you are NOT affected because you ‘know’ that your real beauty lies within your character, within your nature, which no one can ever take away. In that moment you draw on the inner power of that knowledge and use it to remain stable in the face of others negativity. In effect you are drawing on your spiritual strength which is only released when you know who and what you are, and then using that strength in the right way, in the right place at the right time.
