Planets in Leo, and their aspects, tell us through which agencies he is seeking to express the Principle of Power, and by them through which channels his Power consciousness will express in the future. The Sun, however aspected, placed in the fourth house, shows the possibilities of power expression in the maturity of life. The negative aspects to this position show the people or experiences and reactions that will threaten this fulfillment during years of growth. Let us impress on our minds the thought that afflicted aspects involving the Sun are serious problems. The other planets may be in conflict with each other and many problems result thereby, but when the consciousness of power and purpose is stunted, the ability of the person to deal with his planetary difficulties is greatly limited.
Solutions are thus much harder to find and apply.
In other words, the entire horoscope is weakened to the degree that the Sun consciousness is inhibited or depleted. Clarify this thought by imagining the Sun position as the center of activity in the chart, radiating its energies in all directions. The squares and oppositions to the Sun will thus be seen as lines of force from the planets intersecting, or interrupting, these radiations at right angles or head-on from the opposite side of the circle. The planets there show what you want to express, but Leo on the cusp shows how you can best express those urges. Where the Sun is placed shows where we seek to dominate directly and rule our conditions.
