Important warning: intensive prāṇāyāma should only be practiced after purifying the nāḍīs. Otherwise, energy circulates through blocked channels causing problems.

The diseases mentioned can be physical (due to accumulation of energy in congested areas) or mental (such as obsessions or emotional instability).

Prior purification is achieved through ṣaṭkarma, āsana, and gentle nāḍīśodhana prāṇāyāma. Patience at this initial stage is essential.
