'anupada cittassa vimokkhoti nibbanam vuccati' - "The non-clinging citta is meant Nirvana"

"Mind/Citta (is that which) accumulates karma" ( cittena ciyate
karmam) [LXVI, verse 38 Lankavatara Sutra. Trans. D.T. Suzuki]
"The mind/citta is the
Buddha" [gg. 236-239 Lankavatara Sutra. Trans. D.T. Suzuki]
"If no real Self were to exist, then there can be no stages (of
holiness), nor Self-mastery, nor psychic powers (iddhi), nor excellent
samadhi. If the nihilist were to come to you and ask,
'If there is the Self, then show it to me,' the wise will answer 'Show
me your will (and I will show you the Self/Soul).' Those who deny the
Self are opponents of the Buddha's teachings, their
views are one-sided, advocating either 'is', 'is not', these peoples
are to be rejected." [763-765 Lankavatara Sutra. Trans. D.T. Suzuki]

'Etam amatam yadidam anupada cittassa vimokkho' - "This is
immortality, that being the liberated mind/will (citta) which does not
cling (after objectivity)" [MN 2.265]

'anupada cittassa vimokkhoti nibbanam
vuccati' - "The non-clinging citta is meant Nirvana" [MN2-Att. 4.68]
'Samathavipassanaya katham abhisameti Arammane cittam
upanibandhetva pañcakkhandhe dukkhato passati' - "How does one
comprehend samatha and vipassana? Seeing that the
basis for suffering is how the citta
is attached to the five-aggregates (pañcakkhandhe)." [Petekopadesapali
133]
