While studying at the college, Nanalal started writing poetry.
Vasantotsava (
Festival of Spring), a poem, was his first literary composition. His last work
Harisanhita, an epic poem, was published posthumously in three parts during 1959–1960.
Harisanhita, composed in
Anuṣṭubh metre, is considered to be 'a
sublime piece of poetry'. Among the plays that Nanalal has written, the main ones are
Indukumar,
Jaya ane Jayant,
Shahenshah Akbarshah,
Vishvageeta and
Jahangir–Noorjahan. In his social plays, he has discussed the problems of marital love and love-marriage. His plays have thin plot and characters, and their stageability is also limited. These plays are written in
Dolanshaili, a sort of
blank verse based on rhythm, employed by the Nanalal himself. He wrote a biography of his father,
Dalpatram, in three volumes entitled
Kavishwar Dalpatram. The critic
Mansukhlal Jhaveri considers it 'remarkable' for the valuable information it provides about the life in Gujarat some time before and during the life time of Dalpatram. Jhaveri also criticised it for its excessive exaggeration in presentation and the total lack of balance in judging the subject.
Apana Saksharratno (part I & II) and
Gurudakshina are the collections of biographical sketches. He translated several works into Gujarati from
Sanskrit including
Kālidāsa's
Abhijñānaśākuntalam and
Meghadūta;
Bhagavad Gita,
Shikshapatri and 5
Upanishads. ==Reception==
