Śrīmad-Bhāgavatam 1.13.57
Blended reading (Sanskrit + English inline)
Nārada Muni’s prophecy prohibited Yudhiṣṭhira Mahārāja from going to the place where his uncle was staying because even after quitting the body by his own mystic power, Dhṛtarāṣṭra would not be in need of any funeral ceremony; Nārada Muni indicated that his body by itself would burn to ashes. The perfection of the yoga system is attained by such mystic power. The yogī is able to quit his body by his own choice of time and can attain any planet he desires by turning the present body into ashes by self-made fire.
Since Yudhiṣṭhira may try to bring him back Nārada says “Do not be an obstacle (antarāyaḥ)!” Abhūḥ in this case should be bhūḥ with mā, but stays in that form because of poetic license. Yudhiṣṭhira may still want to see him. Therefore Nārada says five days from now (adyatanāt) he will give up his body. Yudhiṣṭhira may want to go to burn the body. Nārada says that he will burn himself up (svam).
