Sant Nirankari Mission : Yug Pravartak Baba Gurbachan Singh Ji
Baba Gurbachan Singh was born on December 10, 1930 in Peshawar, now in Pakistan. After doing his Middle school education from Peshawar, he matriculated from the Khalsa School, Rawalpindi. He, however, could not pursue his studies further, because of the turmoil leading to Partition of India.

During the turbulent days preceding the Partition, every parent wished to be relieved of his pressing responsibilities as quickly as possible. Accordingly, Bhai Manna Singh solemnised the marriage of his daughter, Kulwant Kaur Ji, with Gurbachan Singh Ji on April 22nd, 1947, at a simple ceremony. Kulwant Kaur Ji who subsequently became popular as Nirankari Rajmata.

In India Baba Gurbachan Singh Ji started business in auto-parts, first in Jalandhar in Punjab and later in Delhi. Simultaneously, he took keen interest in congregations. On December 3rd 1962, while addressing a gathering of devotees at Paharganj, Delhi Baba Avtar Singh Ji declared that hereafter this should address Gurbachan Singh Ji as Baba Ji and show him the same respect they had been showing to himself.

Accordingly, Baba Gurbachan Singh Ji started presiding over the Mission from December 3rd, 1962 and the entire Nirankari world saw the Sat guru manifested in him on November 5th, 1963 when they assembled in Delhi for the 16th Annual Nirankari Sant Samagam. Baba Ji vigorously pursued his missionary activities in distant countries and a series of foreign tours for regeneration of mankind were undertaken from 1967 to 1977 almost every year.

Baba Ji gave a clarion call to the youth for propagating the Mission vigorously and combating the social evils. He advised the older generation to give full encouragement to the youth in this direction, failing which they would not only themselves lag behind but also hamper the progress of the Mission. Interestingly, Baba Ji's son Hardev (the present Head of the Mission) and daughters Niranjan, Jagjit, Mohini and Swaran all joined Sewa Dal as its Primary Members. Subsequently all of them made their own mark as disciplined and selfless volunteers, while taking part in different wings of the Seva Dal.

Apart from the spiritual growth of human Baba ji has taken keen interest in the socio-educational atmosphere of the society hence Dispensaries and schools were also set up in various Bhawans. Buildings of two Senior Secondary Schools in Delhi and a Degree College at Sohna, Distt. Gurgaon, Haryana were also constructed as per Baba Ji's plans. Baba Ji took keen interest in homeopathy also.

The voice of truth first raised by Baba Buta Singh Ji and Baba Avtar Singh Ji and now spread by Baba Gurbachan Singh Ji was opposed by the orthodox. The rapid progress of the Mission under the divine leadership of Baba Gurbachan Singh Ji, in fact, upset these elements to the level of desperation. They made an attempt on his life first in Kanpur in Uttar Pradesh and then near Durg in Madhya Pradesh. Ultimately, Baba Ji fell to their bullets in Delhi on April 24, 1980.
