A conjunction (yuti) occurs when two or more planets sit in the same sign of a birth chart, merging their energies. When Sun, Moon and Venus conjoin, the chart blends Sun's the soul, authority and vital life-force, Moon's the mind, emotions and nurturing instinct, Venus's love, beauty and the pleasures of life. This is a mixed combination, with 2 benefic and 1 malefic planets involved.
How the Planets Interact
Sun and Moon are friendly; Sun and Venus are hostile; Moon and Venus are hostile. Friendly planets amplify each other's good results, while hostile planets compete for the same space, creating inner tension that the native must consciously balance. The strongest planet in the group, by dignity, tends to dominate the expression of the conjunction.
Combined Effects
Practically, Sun, Moon and Venus together colour the affairs of whichever house they occupy with a mix of soul (atma), mind (manas), love & marriage. Being a mixed combination, results swing between ease and effort depending on placement.For a precise reading, the sign, house and dignity of each planet in your own chart must be examined together.
