Dvitīyopadeśaḥ (Prāṇāyāma) · Verse 62
गुल्मप्लीहादिकान्रोगान्ज्वरं पित्तं क्षुधां तृषाम् | विषाणि शीतली नाम कुम्भकेयं निहन्ति हि
gulmaplīhādikān rogān jvaraṃ pittaṃ kṣudhāṃ tṛṣām | viṣāṇi śītalī nāma kumbhakeyaṃ nihanti hi
This kumbhaka called śītalī certainly destroys tumors, spleen diseases, fever, excess bile, hunger, thirst, and poisons.
This verse enumerates the therapeutic benefits of śītalī. Gulma (abdominal tumors) and plīha (spleen diseases) are conditions associated with excess internal heat and stagnation. The cooling effect of śītalī counteracts these pathologies.
Jvara (fever) and pitta (bile/fire) are direct manifestations of excess heat that śītalī cools. The practice is especially useful in hot climates or during summer seasons when pitta tends to become aggravated.
Kṣudhā (hunger) and tṛṣā (thirst) are reduced, which is useful for fasting practices. More notable is viṣāṇi — poisons. Tradition affirms that śītalī confers immunity to toxins, including snakebites. Although this should not be tested literally, it reflects the practice’s capacity to strengthen the immune system’s resistance.
