Sun Conjunct Sun Synastry

With Sun conjunct Sun synastry, you can understand each other at a core level. You likely have similar personalities, likes, dislikes, and ambitions.

You inspire each other to shine bright just like the sun. You celebrate each other’s birthday as if it is your own. Through one another, you can see another version of yourself.

You both may focus much on self-improvement. Self-improvement is not selfish. You empower each other to improve yourselves not for personal gain, but for the higher purposes that led you to be born in this world.

Sun Sextile Sun Synastry

With Sun sextile Sun synastry, you encourage each other to become your best self. You both understand that becoming your best self is not about being better than others; it’s about being better than you were yesterday.

You help each other cultivate inner self-awareness and presence. You remind each other that the past holds lessons, and the future holds dreams, but the present holds power. The greatest gift you can give to each other is not presents but presence.

At its core, Sun sextile Sun synastry is a meeting of souls. It is not merely about similarities in your personalities or preferences but about essence—the core of who you are.

Sun Square Sun Synastry

With Sun square Sun synastry, your egos may not like each other. You may have different life goals, moral standards, and values.

There’s a sense of competition in the relationship. You may frequently try to outshine each other. Instead of cheering each other on, you may feel threatened by your partner’s success.

You may also have different approaches to life, decision-making, and self-expression. Each may stubbornly hold onto your perspectives, so compromising can be tough.

Sun Trine Sun Synastry

With Sun trine Sun synastry, you help each other become more self-assured. You remind one another to “know thyself”, because knowing yourself is the beginning of wisdom.¹

You both will learn that the relationship with yourself is the most important relationships in your life. Self-knowledge means recognizing your partner/life is a reflection of who you are.

You not only appreciate each other’s wisdom, but you also respect each other’s father. Or perhaps you can resonate well with one another’s “mature self”.

This aspect enhances natural understanding between you. Your identities, life goals, and values are likely compatible. You’re like two heads living in one body.

Sun Opposite Sun Synastry

With Sun opposite Sun synastry, you are attracted to each other’s differences. You’re trying to balance your life goals, values, and sense of identity.

In this bond, you’re constantly aware of your opposite self. Your partner may represent someone you’re not, but in your differences lie the lesson of harmony.

However, you might often find yourselves locked in power struggles, each trying to pull the relationship in your preferred direction. You tend to dominate rather than cooperate. Self-centeredness can create friction between you.
