Jain meditation (dhyāna) has been the central practice of spirituality in Jainism along with the Three Jewels. Jainism holds that emancipation can only be achieved through meditation or Shukla Dhyana. According to Sagarmal Jain, it aims to reach and remain in a state of "pure-self awareness or knowership." Meditation is also seen as realizing the self, taking the soul to complete freedom, beyond any craving, aversion and/or attachment. The practitioner strives to be just a knower-seer (Gyata-Drashta). Jain meditation can be broadly categorized to the auspicious (Dharmya Dhyana and Shukla Dhyana) and inauspicious (Artta and Raudra Dhyana). The 20th century saw the development and spread of new modernist forms of Jain Dhyana, mainly by monks and laypersons of Śvētāmbara Jainism.
