All seven grahas (the Sun to Saturn) and the lagna held within the arc from Rahu to Ketu - that is, all of them in the six signs on one side of the nodal axis. The twelve named forms (Ananta, Kulika, Vasuki, Shankhapala, Padma, Mahapadma, Takshaka, Karkotaka, Shankhachuda, Ghataka, Vishadhara, Sheshanaga) are named by the house Rahu occupies.
A life read as fated, with struggle, delay and a sense of being carried by something larger than the will; the modern literature gives hardship in the affairs of the houses the axis falls in, and a late or hard-won success.
