Doing one's work honestly means being truthful to one's self. If we create harmony in ourselves, we help to create harmony in the world. If we co-create love and balance, we will have it in our own lives. See the confrontations in life as lessons from God, giving us the chance to learn. To be spiritual is to be conscious of the needs of the self and the needs of others.
Mastery comes from honest effort in our daily lives.
This means that I will look at my life and see what I really have. The key to having what you really need is visualisation. Learn to think in a constructive manner and bring into your life the energy you really need. If you think light, all will be bright. If you think dark thoughts, all will become dark.
