In the full Narada Purana (Purva Bhaga) this is chapter 55, verse 186.
Or it comes in the dasha (planet period) of the strongest planet. Planets in enemy or low signs bring pain. All the planets in two kendra (corner house) places next to each other make Gada. (Our text is unclear here: the word before 'pain'.)
Simple meaning: Kingship can come in the strongest planet's dasha. All planets in two adjoining corner houses make Gada.
