कर्म षट्कं इदं गोप्यं घटशोधनकारकम् । विचित्रगुणसन्धाय पूज्यते योगिपुङ्गवैः ॥ २.२३ ॥

karma ṣaṭkaṃ idaṃ gopyaṃ ghaṭaśodhanakārakam । vicitraguṇasandhāya pūjyate yogipuṅgavaiḥ ॥ 2.23 ॥

Shat-karma (the six kinds of actions) which are a shodhana (detoxification) for the body are secrets. They produce extraordinary attributes and are taken very seriously by the perfect yogi.
