Ruling planets
KSK’s distinctive tool (KP Reader VI): at any moment of judgment, a small set of planets rules the moment, and their agreement with a chart’s significators confirms — or withholds — what the chart promises. The ruling planets are:
- Lagna star lord (fastest-moving, most specific)
- Lagna sign lord
- Moon star lord
- Moon sign lord
- Day lord (the weekday’s planet)
Some practitioners add the Lagna sub lord — KSK treated it as optional, and so does this app (a setting). Two conventions matter and are handled for you: the Hindu day runs sunrise to sunrise, so a pre-dawn judgment keeps the previous weekday’s lord; and a node standing in for a ruling planet — by conjunction, sign or aspect — is itself ruling, and KSK held the agent stronger than the planet it represents.
RPs also power birth-time rectification: scan candidate birth times and keep those whose lagna star and sub lords appear among the ruling planets of the moment you are rectifying — KSK’s own method, which the Rectify wizard automates.
