Vijnana Bhairava 46 47 48 Feeling the Body In Space

The practice of feeling space pervading the body. I am not locked down inside the body or inside anything. Rather, the body and all places are inside me, in the space of awareness :

tanūdeśe śūnyataiva kṣaṇamātraṃ vibhāvayet |
nirvikalpaṃ nirvikalpo nirvikalpasvarūpabhāk || 46 ||
"One shloud feel, just for a moment, 
that very emptiness within the body,
in an undivided manner (nirvikalpam).
Undivided shall enjoy one's undivided essence."

sarvaṃ dehagataṃ dravyaṃ viyadvyāptaṃ mṛgekṣaṇe |
vibhāvayet tatas tasya bhāvanā sā sthirā bhavet || 47 ||
"O gazelle-eyed-one ! One should feel all the substance of one's body
as being pervaded by space.
Then one's feeling shall 
become stable."

dehāntare tvagvibhāgam bhittibhūtaṃ vicintayet |
na kiṃcid antare tasya dhyāyann adhyeyabhāg bhavet || 48 ||
"One should evoke clearly that there is nothing
inside the body,
the skin being like a wall.
Seeing thus, one shall enjoy that which cannot be seen."
