Anukul / Pratikul
Pratikul means a planet that causes evil influence or suffering to the native as seen through the horoscope. This may be a debilitated planet who is in a dusthana and enemy of the lord of the lagna, or otherwise disposed that the influence simply causes suffering.
It is NOT possible to appease a planet which causes suffering by wearing the gem. This is the heart of the pratikul philosophy and causes increased suffering for the persons who are recommended by this method. Mantra, charity, etc. should be advised in such cases solely.
For example if one had a Sag lagna and lord of the ascendant were in the 6th house in Taurus yellow sapphire would be of help in strengthening Jupiter, regardless of the house being a dusthana and an enemy’s sign. For the same lagna, say Sun was in the 8th house in Cancer along with Mars, and there was no correction of debilitation in the horoscope for this. Ruby could be recommended with good results as benefic lord of the 9th, adding that Sun is also a planet that does well in the 8th house.
On the other hand to recommend red coral for Mars would only increase the malefic effects of Mars and cause increased suffering to the native. Were Saturn also debilitated in the 5th, it would be especially foolhardy to recommend blue sapphire as the terrible effects would be even more devastating to the person’s life. Yet were Saturn in Virgo in the 10th, blue sapphire may be worn for increased power in matters of status and career, especially during the Saturn dasha or bhuktis.
An experienced jyotishi must examine the chart from many perspectives before making pronouncements on how a person’s prarabdha karma will manifest in this lifetime and when the effects will be felt. It is not that we quickly see a planet’s position in the rasi chart and make a pronouncement. Careful consideration is always the hallmark of an experienced practitioner of both jyotish and ayurveda in analysis and making recommendations. The same must be true for recommending a gemstone to increase particular influences in a chart. It is true that sometimes increasing a benefic influence may help to overshadow a negative one coming from another quarter, but a bad influence can never be lessened nor curtailed by using the gem for the planet producing it.
