Bal Krishna Sama started the modern Nepali theatre era. Born on B.S. 1959 Magh 24 in Kathmandu, he was a thinker, an outstanding writer, a versatile actor, a successful play director and virtuoso artist of his time. Even today, he is a respected figure in Nepali art and literature.

   The modern Nepali theatre era is said to have begun when Bal Krishna Sama performed the play 'Mukunda Indira' at Durbar High School, Kathmandu in B.S. 1995. It was a turning point in the theater history of Nepali. Then the cast was: Krishna Prasad Rimal as 'Mukunda', Ram Keshari Basnet as 'Indira', Shyam Krishna Bhattarai as 'Bhabadev', Surendra Raj Chalise as 'Biman' and Bopinath Aryal as 'Ramesh Das'. Initially performed for the then, His Late Majesty King Tribhuvan Bir Bikram Shah Dev and the then prime minister, Judha Samsher JBR, this play was later staged numerous times for the general public. It is believed that for the first time ever, the general public had bought the theater ticket to watch the play.

During his four decade long theater life, Bal Krishna Sama had directed 28 plays. He is considered to be the best play director of his time. He also acted in the role of a princess in a play performed in his brother Pushkar Samasher's room for the first time. He went to Kolkata in B.S. 1978 to give his matriculation examinations. In Kolkota, he had the opportunity to watch Shakespeare’s 'Othello' and 'Merchant of Venice', performed by the Alfred Theatre. He was highly impressed and influenced by these stage performances. Similarly, his perception about theatre was also deeply influenced by the English dance performed by the Empire theatre. In his creation 'Mero Kabita to Aradhana (Upasana 1, B.S 1986), he has mentioned that he practiced plays in blank verse.

A writer of many immortal plays, Bal Krishna Sama first directed an English play 'Columbus' in B.S. 1993, and the very next year, he performed his own play 'Prem' at Durbar High School. This is believed to be the first short play of Nepal. After this first play, his most significant play was ‘Prahlad’ in B.S. 1996. The play was first performed at Town Hall in Kathmandu on the very day when the IInd World War started. As this play shook the Rana regime and created a fear of upraising, its performance was banned in the country. Similarly, in B.S. 1997, his play 'Andhabeg' was not permitted to be staged. This was the same year when many men seeking the end of the Rana regime were martyred.

A long time after this, in 2005, he was given a chance to stage the play "Chinta" at Trichandra College, Kathmandu. After Nepal became a democratic country in B.S 2007, he directed the play "Julius Caesar" in which he played the role of Antonio. After this, he directed plays like "Andhabeg” (B.S 2010), "Amar Singh” (B.S 2011), "Hari Tara” (B.S 2013), "Rajendra Lakshmi” (B.S 2013), "Mukunda Indira” (B.S: 2020), and "Pralhad” (B.S 2022). The last play directed by him was "Ameet Basana" in B.S. 2023.

His invaluable contribution to Nepali theatre genre will always be remembered. His work in the Nepali theatre suggests that he was perhaps born for Nepali theatre.
