Shubh Ketu gives spiritual growth, intuition, the path of salvation, secret knowledge, medical perfection and detachment — it turns the soul inward. The afflicted Ketu gives confusion, undue fear, skin/nervous diseases, separation and Kalsarpa-dosha. Ketu is also a shadow planet; Its high/low is scriptural and disagreeable (some consider Scorpio/Sagittarius to be exalted).
To pacify Ketu, chanting 'Om Ke Ketave Namah', worshiping Ganesha and worshiping Bhairav/Shiva are the best. Gemstone Garlic (Cat's Eye) in Silver/Panchadhatu — Fast-effective, so do not wear it without consultation. Food to the dog, donation of blankets/sesame seeds, Ganesh worship and spiritual practice are especially beneficial.
