Scholar Mohammed Ibrahim Joyo recalled that when he took over as secretary Sindhi Adabi Board in 1949, books by Late Shamsul Ulema had disappeared from the market, as Hindu book sellers had migrated to India. He said that as many as 150 articles were published in the Sindhi press against him, simply because in his speech at City College two years later, he had said that Mirza Sahib was above all religious prejudices.

Bherumal Meharchand Advani in "Sindh aen Sindhi" has a biographical sketch of Saiin Mirza Baig. Saiin Advani relates how saiin Baig gave a Sufi interpretation of Islam in his interpretation of Shah Latif. He further writes:
"Personally, [Mirza] was of Sufi leanings and therefore above sectarian differences. When [Judge MungherSingh Lalwani, who was a devout religionist] wrote an interpretation of Jup Sahib [sikh scripture], then Mirza Sahib wrote the Foreward to it in such a manner, as someone praising their guru. When the Dean of the Hyderabad Mission School wanted the 'Book of David' translated [into Sindhi], Mirza sahib proceeded to translate the scripture."

Mirza's pacifist, tolerant philosophy can be summed up by his couplet:
"Fasaada fitne maan naahe, 'kaliija' khe hasili
Pasandi hara kehen khe, muhabata maharbaanii aahe.

"From quarrel and division, Qaleech gets nothing,
Everyone prefers love and kindness."

A retired educationist and an authority on classical music, Dadi Leelawati Harchandani, who is about 80 years old, spellbound the audience with her melodious renderings of Mirza Qaleech Baig's poems.

"Hika diharre murshidi menuu
Sitti ishki dii parrhii."

"One day my teacher to me
Taught one sentence of love."

"Sachuu ishku bbuddha na thive
Torre citti thivaii ddarrhii."

"Oh, Sachal, love does not grow old
Though one's beard turns grey."
