The Prajnaparamita Heart Sutra is said to contain the essence of Truth realized by all Buddhas and Bodhisattva-Mahasatvas. In it's message, it discusses the realization of emptiness, form, etc. As Soto practitioners, and I'm sure in other practices, we chant this every day.
Below are Japanese and English translations, as well as an accompanying video of the chant. May this sutra help you along your path.
Maka Hannya Haramita ShingyoKan ji zai bo satsu. Gyo jin han-nya ha ra mi ta ji. Sho ken go on kai ku. Do is-sai ku yaku.

Heart of Great Perfect Wisdom Sutra
Avalokiteshavara Bodhisattva, when deeply practicing prajna paramita, clearly saw that all five aggregates are empty (ku) andthus relieved all suffering.
Shariputra, form does not differ from emptiness; emptiness does not differ from form. Form itself is emptiness, emptiness itselfform. Sensations, perceptions, formations, and consciousness are also like this. Shariputra, all dharmas are marked by emptiness; they neither arise nor cease, are neither defiled nor pure, neither increase nor decrease. Therefore, given emptiness, there is no form, no sensation, no perception, no formation, no consciousness; no eyes, no ears, no nose, no tongue, no body, no mind; no sight, no sound, no smell, no taste, no touch, no object of mind; no realm of sight… no realm of mind consciousness. There is neither ignorance nor extinction of ignorance… neither old age and death, nor extinction of old age and death; no suffering, no cause, no cessation, no path; no knowledge and no attainment.
With nothing to attain, a bodhisattva relies on prajna paramita, and thus the mind is without hindrance. Without hindrance, there is no fear. Far beyond all inverted views, one realizes nirvana. All buddhas of past, present, and future rely on prajna paramita, and thereby attain unsurpassed, complete, perfect enlightenment.
Therefore, know the prajna paramita as the great miraculous mantra, the great bright mantra, the supreme mantra, the incomparable mantra, which removes all suffering and is true, not false. Therefore we proclaim the prajna paramita mantra, the mantra that says:
"Gate Gate Paragate Parasamgate Bodhi Svaha."
