clinging

clinging ‎(plural clingings)

The act of one who clings.
- 2013, Lawrence C. Becker, Charlotte B. Becker, Encyclopedia of Ethics (page 217)
  The mind […] ascribes characters to things. It can become attached in the process, the attachment taking such forms as erroneous thoughts and clingings, and the Buddha-nature thereby becomes defiled in the way that the sun may be obscured by clouds or a mirror by dust.
