Connecting with the energy of gratitude raises our vibration and is an important tool on days when we feel fearful or depressed. The law of attraction pertains to our thoughts just as much as it does to manifestations of material things. So if you feel depressed, the law of attraction will attract more thoughts of depression to your field, lowering your vibration and leading to a downward spiral of negativity.
Sit with Gratitude when you feel down and within minutes you will feel a lightness coming into your being. This lightness will attract more of the same and in this way, you can raise your vibration.
