With or without intention we are sharing what we have, our inner feelings, our thoughts or overall emotions. All of these are just energy waves that float from the earth to the universe and back.
If you know that something is changing, feel responsible and spread the positive energy to the world. If you feel strong enough help others. Plant as many seeds of love as you can. Grow the love in others and in yourself.
This world is full of people who are just trying to survive the life. Give them a hand and be the channel for messages they need to receive. All you have to do is to stay in a state of love and help for them will come through you.
