Five, ten, sixteen and twenty-four Upacharas are generally offered
to deities during Pooja or Archana. However, sixty-four Upacharas are
prescribed during the Navavarana Pooja of Shri Lalita Mahatripurasundari
Rajarajeshwari ParAbhattArikA in the Shrichakra. These sixty-four
Upacharas are detailed in Vamakeshwara Tantra and in the Parashurama
Kalpasutras. Though it is not possible to physically offer all these
sixty-four Upacharas to Shridevi, by mentioning these Upacharas and
offering the same at the lotus feet of Shridevi using one's imagination,
the merit of actually offering these Upacharas to Shridevi are
obtained. The truth of this statement is confirmed by Shri Bhaskararaya
in his Setubandha and also by Shri Rameshwara Suri in his
commentary on the Parashurama Kalpasutras.
Shri Lalita Chatuhshashtyupachara Samgraha is a hymn, which
beautifully summarizes these sixty-four Upacharas. This hymn, composed
from a high state of consciousness, is the masterpiece of Brahmasri
K. P. Narayana Shastrigal, the late Asthana Vidwan of Mysore State and
DakShinamnaya Shringeri Sharada Peetham and retired professor of
Advaita Vedanta, Chamarajendra Sanskrit College, Bangalore. A scholar par
excellence and a highly accomplished Upasaka of Shri Mahatripurasundari
