Who do not want to undergo the long Durga SaptaShati/Chandi Path. The Siddha Kunjika Stotraitself says at the begining that no argala or kilak stotra and other related matters is needed if one recites Siddha Kunjika Stotra. Kunjika, there is Devi in the form of Chamunda . Not only it works for Navaratri , it is to be chanted at the junction when Ashtami leaves and enters Navami . 24 mins before Ashtami ends to 24 mins after navami starts, is the time when Devi takes the form of Chamunda and had got to be chanted no matter the count to exhaust 48 mins .
How to Count 48 minutes
Each Tithi lasts for 24 hours . If for example the Navami starts at 21.30 pm in the night then you should start at 21.06 (which is Ashtami ) and continue untill 21.54 pm, that 48 mins is called Sandhi kshan or period of transit, when Devi in the form of Chamunda is killing Chanda and Munda (the demons). That is regarded as the most auspiscious time of Navaratri as Devi is ready to give boon after Sandhi kshan is over .
