Twameva Mata Cha Pita Twameva is a very well known and famous stuti mantra or shloka. Twameva Mata Cha Pita Twameva is not just a shloka, its a devine shloka for happiness.
This powerful mantra Twameva comes from the Pandav Gita, an anonymously compiled collection of verses from several ancient sacred Hindu texts (Mahabharat, Bhagavat, and Vishnu Puran). It is also called the song of surrender (Samarpan), as the overarching theme of this sacred hymn is complete surrender to the divine. Its verses are widely chanted by those seeking to experience the wisdom said to be contained therein.
