To make a blog on BAPS Shri Swaminarayan Mandir first you need to know the person who was actually stand behind building up the mandir.
The name of that person, rather I like to describe him as a yogi and an ascetic whose life and teachings brought a revival of central Hindu practices of dharma, ahimsa and brahmacharya, was Swaminarayan, also known as Sahajanand Swami, who is the propagator of the Swaminarayan Sampraday known previously as the Uddhav Sampraday, is a Hindu sect.
A little outside of Kolkata, around 16 Km from Esplanade, the Bhavatarini Mata, an aspect of Kali Mata, founded a temple profoundly known as Dakshineswar Kali Temple situated on the eastern bank of the Hooghly River. The name Bhavatarini meaning ‘She who liberates her devotees from the ocean of existence i.e. ‘Samsara’.
Dakshineswar Kali Temple,formally known as Sri Sri Jagadishwari Mahakali, built up by Rani Rashmoni, a philanthropist and a devotee of Kali on 31st May, 1855.
