Common Reading Pitfalls
Cookbook Reading
Simply reading individual meanings without synthesis
Solution:
Always consider how elements interact. Look for themes, not just isolated meanings.
Overemphasis on Negatives
Focusing only on challenging aspects or placements
Solution:
Every placement has gifts and challenges. Present both sides with growth potential.
Rigid Interpretations
Applying meanings without considering the person's level of consciousness
Solution:
Same placement can manifest at different levels. Consider age, awareness, and development.
Missing the Forest for Trees
Getting lost in details without seeing overall patterns
Solution:
Start with big picture overview. Let major themes guide detailed interpretation.
Ignoring House Systems
Not considering which house system affects interpretation
Solution:
Understand your house system. Consider planets near cusps in multiple systems.
