Bhaja Govindam is the the immortal composition of Adi Sankaracharya, 10 verses of this hymn divinely rendedered by MS Subbulakshmi.
It is said that Adi Shankaracharya, accompanied by his disciples, was walking along a street in Varanasi one day when he came across an aged scholar teaching the rules of Sanskrit grammar to his students by rote. Taking pity on him, Adi Shankaracharya went up to the scholar and advised him not to waste his time on grammar at his age but to turn his mind to God in worship and adoration, which became the origin for this hymn.
