Patanjali's yoga sutras

शब्दज्ञानानुपाती वस्तुशून्यो विकल्प
śabdajñānānupātī vastuśūnyo vikalpaḥ

śabda शब्द – sounds and words that communicate Oneness; the infinite universal sound
jñānānu ज्ञानानु – accompanied by jñāna ज्ञान, insight, knowledge that leads to liberation (from the ego’s likes, dislikes, habits, self-will, and suffering)
pātī पाती – flower offered to Oneness; sacred verse
vastuśūnyo – intangible; vastu वस्तु (tangible things) + śūnyo शून्यो (without)
vikalpaḥ विकल्प – abstract thought

The intangible realm can also be a source of knowledge via abstract thought. Listen for the infinite universal sound to hear insights from your inner voice. Within you are sacred verses, flowers offered to Oneness.

When you open your mind to the reality that everyone and everything are one with the divine whole, this truth will come flooding in from all directions.

There is no place where you do not reside; there is no voice in which you are not expressed. There is no word in which you are not heard; there is no thing in which you do not shine.
