If Rahu is in the lagna at a person’s birth, the native or their wife has a miscarriage or stillborn child. If Rahu is in Aries, Taurus, or Cancer, the native will be kind and will want to enjoy life. If aspected by a malefic, there will be marks on the face.
As a general rule of thumb for Rahu-in-the-1st people, there may be threats to their life but they will be wealthy and powerful. The upper part of their body will be afflicted with a disorder s.t. even if the native cures it, they will be afflicted with another. There could be something foreign about their physical appearance compared to others in their family or society.
They may have a psychological problem like BPD, bipolar disorder, schizophrenia, OCD, hysteria, and other ailments indicated by the extreme nature of Rahu — but the native is also highly intelligent, insightful, and imaginative. They have an extreme mental capacity s.t. they can do any kind of impossible task, especially when combined with Mars or the Sun. Otherwise, it makes the native like an “unguided missile”. They are additionally very good at copying things (memorizing, etc.) and are interested in esoterica, particularly its dark side. They may speak false things in such a manner that nobody can detect their falsehood and they may be materially-oriented.
The native’s mother will either get accused of cheating on her husband or she actually does cheat on her husband. The native themselves will be wanderers. There is also the curse of sarpa (universal energy) in the native’s horoscope. Either their mother or great-grandfather will be the root of such a curse and the native before taking this birth may have been involved.
They are generally non-conformists and have non-conforming opinions on everything from sexuality to politics depending on what planet Rahu is influenced by. For example, if Venus is with Rahu, they might be bisexual or gay or have different views on sex/sensuality. If the moon is with Rahu, they will be afflicted by evil spirits (i.e., they will be possessed, as the moon signifies idleness and Rahu signifies chaos — “blockages” preventing energies from escaping the body) and their unique sort of intelligence derives from that. If Mars is with Rahu, aside from the obvious fact that the native can be a very explosive and angry individual, they will have unique ways of fighting others, getting caught in scandals, owning animals, and wearing nice-looking clothes. There is a high likelihood of the person either being a criminal or disabled if Saturn is with Rahu. If Rahu is with Mercury, both the person’s creativity and crooked intelligence/cleverness increases, they may become eccentric, and they may have knowledge in or take part in the dark arts.
They will be under the influence of others (the particular type of person or gender of the person will depend on the planet influencing Rahu), so the native needs to be aware of who they have in their group. They will have multiple partners but will be detached from them. They change their behavior according to the situation. The native may be thin and have some dullness/bluish to the complexion. Their complexion may be on the dusky side. They may also have crooked or asymmetrical features.
They are prone to suffer from tooth problems, cataracts, skin diseases, sexual perversity, sudden d**th, being killed or murdered, ulcers, gastric problems, speech defects, and insanity.
