Srila Bhaktivinoda Thakura describes in his Bhaktyaloka that there are the karmi, jnani and bhakta. They are all looking for some result from their sacrifices. For one who is engaged in karmayoga, he is looking for the fruit of his sacrifice; he wants some result. The jnani is also looking for some fruitive sacrifice; he wants liberation. The devotee is also looking for some fruit, but the fruit he is looking for is Krishna’s pleasure.
