భారతీ తీర్థ స్వామి సూక్తి

Sri Adi Shankaracharya does not deem everything to be illusory for everyone. Karma, Bhakti and Upasana are all necessary for Jnana – प्राक्ब्रह्मात्मैकतत्वविज्ञानात् सर्वव्यवहाराणामेव प्रामाण्यसिद्धेः – All these are unnecessary only for a Brahma Jnani

The non-dual philosophy of the Upanishads does not decry the Karma enjoined in the Vedas.

There are numerous statements in the Vedas that instruct man to perform Karmas. So if one decries Karma, would not one be attributing falsehood to these statements in the Vedas. Sri Adi Shankaracharya Himself says that one has to accept the authority of the Vedas in totality and not associate authority with only select statements in the Vedas –

न हि वेदवाक्येषु कस्यचित्प्रामाण्यं कस्यचिदप्रामाण्यं इति सम्भवति प्रमाणत्वाविशेषात्

So it is a misunderstanding if one believes that Sri Adi Shankaracharya has given no role for Karma, Bhakti and Upasana. They are all required until the dawn of Brahma Jnana.
