Theory:

     “Let us make him sing Raga Deepak”, he said.
 
     “How will that help us?” asked another man.
 
     “If Raga Deepak is properly sung, it makes the air so hot that the singer is burnt to ashes. Tansen is a very good singer. If he sings Raga Deepak, he will die, and we will be rid of him.”
 
     Shaukat Mian went to Akbar and said, “We don’t think Tansen is a great singer. Let us test him. Tell him to sing Raga Deepak. Only the greatest singers can sing it properly.”
Explanation:
 
Shaukat Mian had plotted a cruel plan against Tansen. He decided to make Tansen sing Raga Deepak. He shared this dangerous plan along with his fellow courtiers. None seem to know the importance of Raga Deepak. Later, Shaukat Mian explained them about the seriousness involved in it.
 
The nature of Raga Deepak is that, if that is properly sung, it makes the air so hot that the singer is burnt to ashes. As they knew very well, Tansen is a very good singer. If a person like Tansen sings Raga Deepak, he will definitely be burnt into ashes. The courtiers agreed upon executing this plan in order to end the bond between Akbar and Tansen. Shaukat Mian met Akbar in person. He cunningly made a complaint on Tansen, accusing his quality of singing. Added to this, he somehow convinced Akbar to make him (Tansen) sing Raga Deepak, claiming that only good singers can sing it.
