Realization, I gt a book lastime.
It says when high root people chant until Samadhi they
enlightened suddenly.
Domo Kun, see in particular the part I highlighted in
green. Samatha and Vipassana must go hand in hand for
realisation to occur. Many so-called highly advanced
practitioners have mistaken jhanic bliss in samadhi to be
insights/realisations, when actually it's not.

Samādhi, or concentration of the mind, is the 3rd
division of the eightfold
path of the Buddha's threefold
training: wisdom
(pañña), conduct
(sīla), concentration
(samādhi) - within which it is developed by samatha meditation.
Some Buddhist schools teach of 40
different object meditations,
according to the Visuddhimagga,
an ancient commentarial text.
These objects include meditations on the
breath (anapanasati), loving
kindness (metta) and various colours, earth,
fire, etc. (kasiṇa).
Important components of Buddhist meditation, frequently
discussed by the Buddha, are the successively higher meditative
states known as the four jhānas
which in the language of the eight-fold path,
are "right concentration". Right concentration has also been
characterised in the Maha-cattarisaka Sutta as
concentration arising due to the previous seven steps of the noble
eightfold path.[19]
Four developments of samādhi are mentioned in the Pāli
Canon:
Post-canonical
Pāli literature identifies three different types of
samādhi:
Not all types of samādhi are recommended either. Those
which focus and multiply the five hindrances
are not suitable for development.[21]
The Buddhist suttas also mention that samādhi
practitioners may develop supernormal powers (abhijñā,
also see siddhis) and list
several that the Buddha developed, but warn that these should not
be allowed to distract the practitioner from the larger goal of
complete freedom from suffering.
The bliss of
samādhi is not the goal of Buddhism; but it remains an
important tool in reaching the goal of enlightenment.
Samatha/samādhi meditation and
vipassana/insight meditation are the two wheels of the
chariot of the noble eightfold path and the Buddha strongly
recommended developing them both.
