Count the stars beginning fron the star of the girl. If such counted number comes as 2,4,6,8,9,11,13,15,18,20,24,26, it is good and agrees. If Rohini, Ardhra, Maka, Visaka, Sravana, Hasta, Uttarashada, Revathi happens to be the same star for girl and boy they agree.
In cases of Mrigasira, Aswani, Krithika, Punarvasu, Pushya, Uttara, Chitra, Uttarashada, Purvashada stars, if they are same they also agree but are given secondary choice. Others do not agree.
In cases where the two stars are same it is good that the signs of the boy leads that of girl. 27th star even in different signs has to be rejected.
