His name is Heera Panna. A rather colourful name for a Kannadiga from Benglur. However, nobody except his close friends call him by the name his parents gave him. To the world, he is known as Dasappa. Because that's his profession.
Heera Panna is a Dasappa who goes from home to home, doing pooja and distributing blessings in the name of Lord Venkateshwara of Thirumala Thirupati. A profession that is practised only for two days in a week. Friday and Saturday.
On a Friday, it makes senses for Dasappa to walk up and down the mains and crosses of Gandhinagar. Because that's the day for movie openings. He's likely to have film producers and distributors asking Dasappa to convey their prayers to the Lord of Seven Hills in Thirumala, AP, for a small fee.
