आसनानीह तावंति यावंत्यो जीवयो नयः । सिद्धासनमिदं प्रोक्तं योगिनो योगसिद्धिदम्
āsanānīha tāvaṃti yāvaṃtyo jīvayo nayaḥ | siddhāsanamidaṃ proktaṃ yogino yogasiddhidam
在此,坐法多如众生的种种形态与动静。然而此“悉地坐”(Siddhāsana)被宣说:能赐予瑜伽行者瑜伽成就。
Skanda (deduced: Kāśīkhaṇḍa commonly Skanda → Agastya)
Tirtha: Kāśī (yoga-sādhanā within kṣetra)
Type: kshetra
Listener: seekers/ṛṣis (contextual)
Scene: A yogin in Siddhāsana, heels set, spine erect, hands in jñāna-mudrā; around him faint silhouettes of animals/birds in varied postures to symbolize innumerable āsanas; the yogin remains the still center.
Among countless postures, Siddhāsana is singled out as especially effective for attaining yogic steadiness and success.
Within the Kāśīkhaṇḍa context, Kāśī is the broader sacred setting where such yogic means are taught toward mokṣa.
A practical prescription is given: adopt Siddhāsana as a posture conducive to yoga-siddhi.
