sub-sub arc is practically ultimate division and Cuspal sub-sub lord is the agent who interacts with other Cusps and Bhava. The interaction or inter-relationship of Cuspal sub-sub lords with other Cusps/ Bhava is termed as Cuspal Interlinks. In Cuspal Interlinks Theory Mr. S.P. Khullar has uniquely described all about the interaction and inter-relationship of Cuspal sub-sub lords.
In other words, a planet relates with others cusp or becomes significator of that cusp(s) where the lord of star of a planet appear in the Cuspal position. It is termed as the planet involved the cusp through its star lord. Likewise, wherever sub lord of the planet appears in Cuspal position, it understood that the planet committed to the cusp through sub lord. If this committed cusp is in favourable position with respect to involved cusp then we say that the planet is fruitful significator of the involved cusp (where planet’s star lord has appeared). The Sub Sub Lord of Sub Sub Lord of planet will declare the culmination of the involvement and commitment of the planet. That is, Sub Sub Lord of Cuspal Sub Sub Lord is a planet that gives hint of fruitfulness of the significationship of the planet for involved cusp(s). Clearly, a planet becomes significator and gives result of only those cusp(s)/ Bhava where star lord of the planet appears. It becomes fruitful significator of those cusps if the planet is favourably com mitted.
