“Lean not on your own understanding” means not to only trust what you perceive with your five senses. There is more to this planet than what you see, hear, feel, taste, and smell. Your understanding of life is increased by the gift from God: intuition.
This sixth sense is your Higher Power guiding you in the right direction. Intuition is always your first thought about a situation. The thought is usually quick and fleeting. Sometimes intuition is felt in your body, a la “I had a gut feeling about……”
Listening to your intuition is a skill to be cultivated in order for you to trust it. That’s why meditation or even quiet time with no media distractions is helpful. They both teach you to listen to your own inner wisdom.
Mantra: I trust my intuition today.
