Spontaneity means acting naturally and effortlessly. Spontaneous energy is rooted in your very center of being.
For example, your four-year-old playfully splashes water on you and is looking forward to your response with an air of innocent amusement. One option is to reprimand and lecture him on good behavior and then get back to cleaning up the mess. The other option sees the bigger picture, i.e., look beyond his act to understand his desire to engage with you. When a spontaneous person responds to the moment, he or she is accepting complete responsibility for that moment and is open to the interesting possibilities of life. Spontaneous action generally leaves you feeling joyful, liberated, and full of gratitude for life.
But when our behavior does not arise from within us or is superficial, it becomes a reaction rather than a response.
For example, during a fight, you get caught up in the heat of the moment and say many things, which you regret later. Driving rashly, speaking rudely, or indulging in repetitive mindless tasks are examples of impulsive behaviors.
Impulsiveness is rooted in the ego (the false outer image of the self), driven by our baser instincts, and accompanied by guilt, regrets, or misery.
When you are in the now, your memories don’t pull you back, and your future expectations no longer confine you to a limited set of possibilities.
