The balance needs to be found in relationships between love and truth. All relationships are based on the dimension of depth, and real intimacy, love, or sharing with others cannot take place unless a high degree of truth is part of the relationship.
If you are afraid to be truthful because it will hurt another or cause greater separation, then consider this: that the absence of truth is already creating a separation and limiting what another can share with you and you with them. Souls help each other by encouraging each other to be more real. This is the meaning of "when you set yourself free, you set others free as well." It is why souls come together in the highest sense - to help each other into greater wholeness.
