The term 'NATURAL impulse' can be broken down into two words: 'NATURAL' and 'URGE'. The word 'NATURAL' is defined as something that exists in or is caused by nature, while the word 'URGE' is defined as a strong desire or impulse to do something. Together, these two words can be interpreted to mean an instinctive or innate desire to do something. This could be anything from a desire to help someone in need to a desire to explore new places. NATURAL impulses are often seen as a part of human nature, and they can be both positive and negative.
