Answering questions from thronging newspersons, Parrikar, who took oath on Sunday and was allocated his portfolio late in the night, said he is "feeling proud" to have filed his Rajya Sabha nomination papers from Uttar Pradesh.
Parrikar said he was "feeling honoured" to represent the state in parliament. "I consider myself lucky," he added.
To a question, a smiling Parrikar, who quit as Goa chief minister on Saturday, said he came to know of his portfolio at 11.35 p.m. on Sunday.
He said he needs to study his new ministry properly, before making any comments. "I will study it properly and reply later," he told clamouring newspersons.
He said his aim would be "targeted completion of whatever is required to strengthen India", he said.
