ये त्वेतदभ्यसूयन्तो नानुतिष्ठन्ति मे मतम् । सर्वज्ञानविमूढांस्तान्विद्धि नष्टानचेतसः ॥

ye tv etad abhyasuyanto nanutisthanti me matam sarva-jnana-vimudhams tan viddhi nastan acetasah
Translation
But those who carp at My teaching and do not practice this teaching of Mine —know them to be seriously deluded and devoid of reasoning, and therefore lost.
Purport
In earlier Shloka Bhagvan Shri Krishna explained that those devotees who perform their duties taking refuse and submitting all actions to Shri Krishna are liberated from the bonds of actions.
In this Shloka, Bhagvan Shri Krishna explained that those who do not take his words and rather ridicule the path of Karma and duties fall into the grip of physical desires and end up being deluded and lost Their future is uncertain.
