Leelamma has performed Mohiniyattam at numerous venues in India and abroad and has run her own institute called Swathi Chitra in Atthani,
Thrissur district, to conduct research on Mohiniyattam. Leelamma gone beyond the traditional Mohiniyattam dance performances by directing her own Mohiniyattam adaptations. Leelamma assimilated the possibilities of performing the emotion of fear into Mohiniyattam, through her directions like the Narasimha avatar performance with the kirtana that begins with 'Shriman Narayana', and Hiranyakashipu. Through these directions she invalidated the unwritten rule that only soft emotions like love, devotion, and compassion are applicable in Mohiniyattam. The kirtana, which began with 'Kamitavaradayaka', which made Shiva the main character instead of Vishnu, was also a new step in the history of Mohiniyattam. Leelamma expanded the stage possibilities of Mohiniyattam by adding different and unique heroines from Indian mythological stories to the conceptual sphere of Mohiniyattam. In addition to traditional
kirtans, Leelamma has directed and presented famous Malayalam poems and other works in the Mohiniyattam form. Examples of these include
Vallathol's poems
Magdalana Mariam,
Shishyanum Makanum,
Achannum Makanum,
Kumaranasan's poem
Veenapoovu,
Vailoppilly's
Mampazham,
O.N.V.'s

Mohiniyattam Siddhantavum Prayogavum (meaning: theory and practice of Mohiniyattam), written by her comprehensively describes Mohiniyattam. ==Awards and honors==
