In Buddhism
Mahayana (major branch of Buddhism)
Source: Wisdom Library: Maha Prajnaparamita SastraSamādhirājasamādhi (समाधिराजसमाधि).—According to the 2nd century Mahāprajñāpāramitāśāstra (chapter XIV), “then, having himself arranged the lion-seat, the Bhagavat sat down cross-legged; holding his body upright and fixing his attention, he entered into the samādhi called King of Samādhis (samādhirājasamādhi), in which all the concentrations are included”.
What is the samādhirājasamādhi? This samādhi is foremost among all the samādhis; it takes innumerable samādhis at will as object. Just as the king (rājan) is foremost of all men, just as the cakravartin king is foremost among kings, just as the Buddha is foremost among all the beings of earth and heaven, so this samādhi is foremost of all samādhis.
When he has entered samādhirājasamādhi, the Buddha, with his six super-knowledges (abhijñā), penetrates the ten directions without obstacle or limit. When he has entered samādhirājasamādhi, he manifests his great miraculous power (ṛddhibala) by means of all kinds of metamorphoses (nirmāṇa).

Mahayana (महायान, mahāyāna) is a major branch of Buddhism focusing on the path of a Bodhisattva (spiritual aspirants/ enlightened beings). Extant literature is vast and primarely composed in the Sanskrit language. There are many sūtras of which some of the earliest are the various Prajñāpāramitā sūtras.
