Dear friend i think you are confusing two very different concepts... kundali and kundalini...

Kundali is the horoscope and is a part of vedic astrology ...the "yog" as defined mean periods where those happenings can have maximum possibility... like wedding, wealth, death

Kundalini is a shakti which is a untimate of meditation and which is aquired as a end result of pursuit of Yogas as hatha yoga, gnanya yoga, sankhya yoga... the awakening of the kundalini is assciated with many miracles menifesting in a human being in whom the shakti awakens.
