Yes, Aquarius rules your 5th house. And Saturn rules Aquarius.
The grand trine contains your mercury, trine both positive Jupiter and serious Saturn, so you tend to think on emotional lines.
You know your moon is in Leo, and this is your emotional expression.
Saturn is in the compassionate sign of pisces, who also rules your 6th house of healing, and mercury in the 9th of religion, spiritual issues and higher learning, rules your 12th of introspection, institutions and hospitals.
Jupiter, who completes the trine rules your 6th house as well as the 3rd of communications, and sits on your 2nd of income.
You have a lot of potential here as a communicator and healer, or one who writes about spiritual issues and healing, and it would provide a good income for you as well. Have you ever thought about this?
With Saturn ruling the 5th it could be also communications directed specifically towards, meant for, children.
