English Translation of Sanskrit Commentary By Sri Shankaracharya's
4.15 Jnatva, having known; evam, thus, that I am not an agent; I have no desire for the results of actions; karma, duties; krtam, were undertaken; api, even; purvaih, by the ancient; mumuksubhih, seekers of Liberation. Tasmat, therefore; tvam, you; kuru, undertake; karma, action; eva, itself. You ought not to sit ietly, or even renounce.

[This last portion of the sentence is translated by some as follows: You should not undertake actions which are done in the present manner (i.e. do not perform actions in the manner undertakne by people nowadays, which neither purifies the mind nor helps people).

English Translation of Ramanuja's Sanskrit Commentary
4.15 Actions of the kind described above were performed even by the aspirants of old for liberation, who have become free from evil after knowing Me in this way. Therefore, after having got rid of the sins by knowledge of Me in the aforesaid way, perform actions in the same way as they were performed by those ancients like Vivasvan, Manu etc., in olden times, in the way in which their performance was taught by Me even then. I shall declare it again in what follows.

Sri Krsna stresses the difficulty of undertaking the type of Karma that is going to be taught now.
