Hello,
I would like to ask something regarding the rulership of cusps. In the beginning i thought it is handled like the house rulership, so when mercury is scorpio - mars rules the house/sign and therefore also mercury, not mercury rules the house. But in some videos its not clear for me because sometimes if for instance the second cusp falls in scorpio and mercury is in the sign - it is said that mars rules the cusp and other times it is said that mercury (also) rules the second cusp.
Thank you for help.
We look at the signs and their rules when we assess the yogas. And also what´s going on with that bhava, but more in a psychological or inner way. The person´s attitude towards the thing that the bhava represent.
The cusp is like the birthplace for the concrete manifestations of that bhava.
I hope this answers your question, although I understand that it might not. And perhaps you knew it already.
