Bhagat Trilochan Ji has four hymns in the Guru Granth Sahib Ji. He was a Vaishya of Maharashtra, a contemporary and associate of Bhagat Namdev Ji.
His compositions turn on the moment of death and what the mind is fixed on at it. One of them, in Gujri, describes a man dying with his thoughts on his wealth, his children, his property and his cattle, and what he becomes as a result of each. It is quoted in Punjab in ordinary conversation about attachment.
Little is known about him beyond the association with Namdev Ji. He is one of several Bhagats in the volume whose biography is thin and whose text is not.
The other three are in Sri raga and Dhanasari and they go at the reckoning of days and the observance of auspicious times, saying that a man occupied with when to do a thing has already missed the thing itself. It is one position argued four ways.
Bhagat Namdev Ji is recorded in the Varkari tradition as having been in contact with him, which places him in thirteenth or fourteenth-century Maharashtra, and the Sikh tradition preserves nothing further.
That the volume contains four hymns by a man about whom nothing else is known is characteristic of its editorial principle: the composition was judged and the credentials were not asked for.
