As a child he used to accompany the village congregation to Rara Sahib. But
in 1948 he finally resolved to settle at Rara Sahib under the aegis and
patronage of Sant Isher Singh Ji and undertook the devout services of
the sanctum sanatorium. Delighted with his services the patron saint made him in charge (Shrimaan)
of the community kitchen (Guru Ka Langar). He dispensed this service regularly for six years.
He also served in the farm of Gurdwara Sahib for a brief spell.
Sant Teja Singh Ji has been keenly devoted to the Gurbani. Besides the 'Banis' of 'Nitnem'
and 'Panj Granthi' he has learnt
most of 'Shri Dasam Granth Sahib' by heart. Sant Isher Singh Ji used to
be charmed by his recital of Gurbani. It was Sant Teja Singh Ji's love for the Gurbani that
brought him closer to Sant Isher Singh Ji. Besides reciting Gurbani to
his patron and mentor, he prepared meals for him. He used to accompany his mentor and perform
the 'ardas' at the termination of each congregation (The Diwan).
After Sant Isher Singh Ji left for his heavenly abode, Sant Teja Singh
Ji was entrusted upon the services of the 'Bhora Sahib', which he is performing hole heartedly
to this day.
On 10th January 1990, all the religious organizations, the chiefs of different Sikh communities,
the sangat of the surrounding areas and Gurdwara Karamsar Rara Sahib Trust bestowed all the
responsibilities of care and service of the Gurdwara upon Sant Teja Singh Ji. Despite spending
most of his time in the Bhora Sahib (the privy chamber of Sant Isher Singh Ji)
the present Sant Ji is shouldering all the responsibilities of Gurdwara Sahib perfectly well
with the co-operation of the 'Gurdwara Karamsar Rara Sahib Trust'.
