Chitragupta (Sanskrit: चित्रगुप्त, 'rich in secrets' or 'hidden picture') is a Hindu god assigned with the task of keeping complete records of actions of human beings on the earth. Upon their death, Chitragupta has the task of deciding heaven or the hell for the humans, depending on their actions on the earth. Chitragupta Maharaj (Chitragupta the King) is the patron deity of Kayasthas, a Hindu caste of India.

Chitragupta came into being after Brahma, the creator, having established the four varnas — Brahmin, Kshatriya, Vaishya and Shudra — ordained Dharamraj (also called Yamraj, the god of death) to keep record of the deeds — good and evil — of all life-forms born and yet to be born on earth, in the heavens above and in the lands below. Dharamraj, however, complained, "O Lord, how can I alone keep record of the deeds of the beings born into 84 lakh yonis (life-forms) in the three worlds?"

Brahma went into meditation for 11, 000 years and when he opened his eyes he saw a man holding pen and ink-pot in his hands and a sword girdled to his waist. Brahma spoke: "Thou hast been created from my body (Kaya), therefore shall thy progeny be known as the Kayasthas. Thou hast been conceived in my mind (Chitra) and in secrecy (gupta), thy name shall also be Chitragupta." Brahma then enjoined him to dispense justice and punish those who violated the dharma (duties).

Lata Mangeshkar (born September 28, 1929) is a singer from India. She is one of the best-known and most respected playback singers in India. Mangeshkar's career started in 1942 and has spanned over six and a half decades. She has recorded songs for over a thousand Hindi films and has sung songs in over thirty-six regional Indian languages and foreign languages, though primarily in Hindi. She is the elder sister of singer Asha Bhosle, Hridayanath Mangeshkar, Usha Mangeshkar and Meena Mangeshkar. She is the second vocalist to have ever been awarded the Bharat Ratna, India's highest civilian honour.

Mangeshkar was featured in the Guinness Book of World Records from 1974 to 1991 for having made the most recordings in the world. The claim was that she had recorded approximately 25,000 solo, duet, and chorus-backed songs in 20 Indian languages between 1948 to 1974. Over the years, while several sources have supported this claim, others have raised concerns over its veracity, claiming that this number was highly exaggerated and that Mangeshkar's younger sister, Asha Bhosle, had more song recordings than she had. In 2011 Guinness officially acknowledged Bhosle as the most recorded artist in music history.

At that time, his mother decided to take the bold step of leaving her husband, forfeiting all claims to the financial assets. Sahir's father then sued his mother for child custody but lost. He threatened to make sure Sahir did not live with his mother very long, even if that meant taking the child's life. Sahir's mother then found friends who kept a close watch on him and didn't let him out of sight. Fear and financial deprivation surrounded the formative years of this young man.
