Sai Samsthan USA has been organizing worship services since its inception. A special worship service on every Thursday evening include Samoohika Vishnu Sahasra Nama Parayana, Shri Sai Ashtothara, Sri Sai Satcharita Parayana Bhajans/Kirtans, and Shej Arati followed by Mahaprasad. In addition, all major religious functions such as Sri Rama Navmi, Guru Pournima, Gokul Ashtami, Maha Shivaratri, Baba’s Maha Samadhi Day and Datta Jayanti are celebrated with utmost devotion. As the demand for these services increased with enthusiastic participation of ever increasing number of devotees, Samsthan employed two full time priests. Pandit Shri Ravivardhan Bhattachar ji and Pandit Sandeep Purandare ji acquired knowledge of ‘Shodasanta Smartam’ and other vedic and agama rituals under the tutelage of Acharyas in Sringeri Karnataka India.
Sai Samsthan USA tirelessly searched and found a place to establish Shri Shirdi Sai Baba Mandir Chicago. With the Grace of Baba, Samsthan purchased approximately 5.5 acres of land in Aurora, Illinois and inaugurated Shri Shirdi Sai Baba Mandir Chicago on December 19, 2002, Pournima Thursday, Shri Datta Jayanti Day. a combination that occurs only once in 62 years. Daily worship services and four Aratis are performed at this location. Shankhusthapana (Ground Breaking Ceremony) was performed from August 26 – 29, 2004 culminating in placing ‘Shankha’ on August 29, 2004, the auspicious Shravana Pournima day. Shilanyas (Foundation Stone Laying Ceremony) was performed on May 22, 2005, the auspicious Buddha Pournima day. Mandir construction was completed and ‘Kumbhabhishekam’ was performed from July 6 – 15, 2006 with ‘Murti Prana Pratishtha’ on July 11, 2006, the auspicious Guru Pournima day. Mandir facilities now include old prayer hall, main mandir, a multi-purpose hall, kitchen and an expanded parking. Mandir also acquired adjacent property to conduct Sunday school, Bala Vidya Mandir for children and also for priest’s residence.
Last but not the least, Sai Samsthan USA organizes SHIRDI SAI MAHOTSAV, an International Congregation of Sai Devotees. every year during the Labor Day week-end.
