One useful way to regard the Holy Trinity is to apply it to that triune part of yourself—your head, your heart, and your will. There are certainly other parts just as real, but these seem to form the main three.
By working in threes, we gain an advantage over focusing on one aspect at a time, because in reality all activity, whether personal or cosmic, has this same tripart expression. When we look at manifestation, things take on a four-part structure. But we will go into that when we consider the third basic symbol, the square.
In working with our head, our heart, and our will, we naturally rise up out of our generative nature and begin to see ourselves as more than a body. We start to become aware of ourselves as energetic beings—spiritual, intellectual, and alive.
Whereas the number two speaks of polarity and potentiality, the number three speaks of dynamic balance.
By focusing our attention on our head, our heart, and our will simultaneously, the three get to know each other in relation to themselves.
These three currents of God find their point of expression in us, and we get to witness their outworkings in our consciousness. Whatever task we set about, we bring a complete set of spiritual tools with us.
Normally, we approach the world with only one of these aspects, or at least we find that one is predominant. This forms a distorted triangle, which symbolizes a state of imbalance.
If we are all mind, we become too analytical, and we get caught up in the many choices life has to offer, but we are unable to choose among the many alternatives.
If we are all heart, we lose the ability to discriminate, to make distinctions. The world begins to blend together, not as a unified whole but as pool of interpenetrating awarenesses. This can be wonderful, but joy can quickly turn into sorrow, and sorrow into despair. The world seems to always be happening to us and not because of us.
And if we are all willpower, we are great at getting things done, but it is usually at the expense of others. We become the hammer that sees everything as a nail. But, instead of joining things together, we break them apart. And though we are good at starting things, rarely are we able to bring them to a meaningful conclusion.
So, achieving a balance of these three aspects brings a powerful harmony into our lives. How do we do this? Simply by focusing our awareness on them and then observing how the energy moves. We do this through the three activities of concentration, meditation, and contemplation. We learn to focus our awareness, we learn to be receptive to our higher nature, and we learn how to interact with what comes. These are the tools we have in our quest for Self-realization.
