In Hinduism
Purana and Itihasa (epic history)
Source: archive.org: Shiva Purana - English TranslationSudṛḍha (सुदृढ) (Cf. Dṛḍha) refers to “resolute” (i.e., “very firm”), according to the Śivapurāṇa 2.3.25 (“The seven celestial sages test Pārvatī”).—Accordingly, as Pārvatī said to the seven Sages: “[...] This mind of mine is resolute [i.e., sudṛḍha] helplessly attempting at a great task. Verily it is trying to erect a high wall on the surface of water. At the bidding of the celestial sage I am performing this steady penance with the desire that Rudra be my husband. The unfledged birdling of my mind flies up tenaciously. May lord Śiva, the storehouse of mercy fulfil its desire”.

The Purana (पुराण, purāṇas) refers to Sanskrit literature preserving ancient India’s vast cultural history, including historical legends, religious ceremonies, various arts and sciences. The eighteen mahapuranas total over 400,000 shlokas (metrical couplets) and date to at least several centuries BCE.
Yoga (school of philosophy)
Source: ORA: Amanaska (king of all yogas): A Critical Edition and Annotated Translation by Jason BirchSudṛḍhā (सुदृढा) refers to “very steady”, according to the Mataṅgapārameśvaratantra (Mataṅgapārameśvara’s Yogapāda) verse 2.23-27.—Accordingly, while discussing ancillary and seated poses in Yoga: “[...] Having raised and broadened the chest and having made the arms loose, the wise [Yogin] should extend his back and raise the region of the shoulders. He should diligently hold the neck still, very steady (sudṛḍhā) and straight [but] not too rigid nor bent [to one side]. [...]”.

Yoga is originally considered a branch of Hindu philosophy (astika), but both ancient and modern Yoga combine the physical, mental and spiritual. Yoga teaches various physical techniques also known as āsanas (postures), used for various purposes (eg., meditation, contemplation, relaxation).
