The former US President shared the letter in its entirety on 'Medium': "Read to the end" of the note, he writes, adding "you won't regret it."
The letter, which was sent to Obama on January, was written by Sindhu who is a feminist and a mother. She had heard Michelle speak in 1996, the Elle.Com reported.
"I'm proud of Michelle for the difference she made in this young woman's life, and I'm inspired by Sindhu's story-so I thought I'd share it with you today," Obama prefaced Sindhu's letter.
She wrote, that week, she signed up to be a volunteer at the hospital and signed up for an after-school programme teaching creative writing and literature for underserved children in the community.
"I later found out that the inspirational powerhouse of a woman who spoke was Michelle Obama. I wanted to say thank you to the both of you. Thank you, Michelle, for helping a vulnerable teenager raised to comply to start to challenge the notion that she was powerless," Sindhu wrote.
"I am now a middle-aged Indian woman who is married to an Indian feminist man and raising a feminist 3-year-old son (whose middle name is Atticus and who thinks he is actually Thomas the train.) They are amazing, she adds.
"The ways in which you have impacted the world have left me expecting so much more from our world. And I know that this is not an expectation I can have without being part of that change. The events from this week, this amazing women's march, echoed globally that the expectations I have are not ones I hold in isolation. I want a different world. I need a different world," Sindhu wrote.
