Patanjali's yoga sutras

तदेवार्थमात्रनिर्भासं स्वरूपशून्यमिव समाधिः ॥ ३.३ ॥

tadevārthamātranirbhāsaṃ svarūpaśūnyamiva samādhiḥ || 3.3 ||

tad = that

eva = the same

artha = object, place, point

matra = only, alone

nirbhasam = shines forth, appears

svarupa = own form, own nature (sva = own; rupe = form, nature)

shunyam = devoid of, empty

iva = as if, as it were

samadhih = meditation in its higher state, deep absorption of meditation, the state of perfected concentration

Cosmic Consciousness is when only the essence of your focus shines forth, as if empty of its own form. In this state, you experience a merging with that essence, as your form falls away, too. In these moments of Oneness, you know that you are an integral, inextricable, essential, and indivisible part of the omnipresent, omniscient, omnipotence that is the living organism we call the Universe or Existence.
