Rahu is okay in this house. Mercury rahu are friendly to each other. But not by sign.
Since you’re in mercury mahadasha. You need to see where mercury is placed.
If it debilitated. Then that’s not good. It can affect your mental ability to think. And damage your image In the society. If it exalted in Virgo. Then it’s good but he might give you some unnecessary health issues. And over spending nature of money.
Mercury is fast moving planet. So during mercury dasha. Lot of travels is expected.
You should focus on the mercury side as it is the main active dasha as for now. Mercury dasha lasts for 17 years.
Rahu antardasha is okay. Since it is in 3th house. Which rules your speech. Siblings and communication. during this bhukti you will be inclined toward spreading your philosophical
Knowledge with people. Because it is placed in Pisces by sign. It tend to gives you mental worries too. Since it is the sign of water itself. And tend to bring lot of weird vivid dreams during this antardasha of rahu.
The prana of ketu. Just beaware of accident. It tend to happen during ketu bhukti. Ketu is hidden so should be careful. During this time you also incline toward learning occult science. Because the nature of ketu.
Need to check where mercury is place. Rahu is highlighting lot of mercury in here.
Yea they’re friendly planets. As for mercury. But not rahu toward moon. So there will be lot of tension during this rahu bhukti. Because it is conjunt with venus too. Rahu will enhance this part. He makes you indulge toward pleasures. Of all kinds. Sex money and whatever it is. That’s venusian energy.
So expect some tension in this regard. And druing this peroid. Since moon is there. Your connection with your mother or any females might be not well. Be careful of that. Just stay calm is the best thing you can do to manage the situation. Chanting rahu mantra could be beneficial during this peroid. Avoid anything that represents rahu. Such smoking cigarettes. Avoid consumption of alcohol too is important. And meat.
Another thing to mention.
Since you are in mercury dasha. Your life is ruled by mercury now. So the impact of budh is strong.
Mercury is in retrograde. This impact can significantly affect you. Its the main dasha for you now. He retrograde In Pisces. So this affect your subconscious mind. Not sure what is your ascendant though.
eta: @Nyxia if guided PU’s Mercury Healing and Development is perfect for your Mahadasha. I use Venus for my MD, and I’m just happy with the results Cap’s Rahu Homam for Antardasha. I use that, we have the same dasha. Thankfully, we have remedies and tools that can help.
The Nakshatra of rahu is ruled by shani himself. So there is still some help coming from friendly planet that support rahu himself. But looking at where the lord is placed still in the Nakshatra of budh himself. By house Shani is not good though. But yea generally your mahadasha is not as bad judging from it. You gain a lot but at the same time losing is inevitable. So there need to be cautions during bukti of rahu. But you will be fine. It seems you are now in antardasha of Jupiter himself. Up to 2025.
