d60 and current life troubles

[bowly]

greetings all

I recently stumbled upon an article about d60 and the current life upheavels..acc to that, during the moola dasha of a planet that's debilitated in d60 we undergo troubles and loss of near n dear ones in the vimshottri maha or antar dasha of the d1 chart ..

can anyone help explain what each house signfy in terms of curse or bad karma from past life and why some planets though good in d1 give adverse result during its moola dasha.

help appreciated
