The “Sama Sankhya” rule applies only to the relationship between Gayatri Japa and Ashtaksharam. That is, how many times you perform Gayatri Japa, you should chant the Ashtaksharam the same number of times. Regarding other mantras, our tradition suggests chanting them as much as possible—perhaps in counts of 10, 28, or 108, depending on one’s ability.
