Sanskrit

देहान्तरे त्वग्विभागम् भित्तिभूतं विचिन्तयेत्।
न किञ्चिद् अन्तरे तस्य ध्यायन्न् अध्येयभाग् भवेत्॥ ४८॥

Transliteration

dehāntare tvagvibhāgam bhittibhūtaṁ vicintayet|
na kiñcid antare tasya dhyāyann adhyeyabhāg bhavet|| 48 ||

Translation

One should contemplate on the skin of the body as a mere wall or partition with nothing inside it. By meditating thus, he becomes like the void, which cannot be meditated upon.
