Over the years the temple, situated 17 km from Nainital on the Nainital-Almora road, has become an important pilgrimage for locals, as well as spiritual seekers and devotees worldwide.

[8][9][10] Neem Karoli Baba died at approximately 1:15 a.m. on 11 September 1973 in a hospital at Vrindavan, India,[11][12] after slipping into a diabetic coma.

He had been returning by night train to Kainchi[13] near Nainital, from Agra where he had visited a heart specialist due to experiencing pains in his chest.

He and his traveling companions had disembarked at Mathura railway station where he began convulsing and requested being taken to Shri Dham Vrindavan.

Maharajji roused and pulled the oxygen mask off his face and the blood pressure measuring band from his arm, saying, "Bekar (useless)."

Neem Karoli Baba was a lifelong adept of bhakti yoga, and encouraged service to others (seva) as the highest form of unconditional devotion to God.

[17] Siddhi Ma is a prominent figure in the spiritual lineage of Baba Neem Karoli Maharaj, renowned for her unwavering devotion and significant contributions to the community.

Following her husband’s death, she made a profound commitment to serve Baba, ultimately sacrificing her family life to devote herself fully to spiritual pursuits.

When Baba Neem Karoli Maharaj attained Brahmaline status in 1973, Siddhi Ma was chosen as his successor, taking over the management of the Kainchi Dham temple complex.

Siddhi Ma regularly held darshan sessions for devotees at Kainchi Dham, typically on Saturday and Tuesday.

After her passing on December 28, 2017, at the age of 92, a grand statue of Siddhi Maa was installed at Kainchi Dham, alongside the construction of a dedicated pooja room.
