As with Prāṇāyāma, the role and practice of Mudrā
needs to be considered from two distinct, but
complementary and developmental viewpoints.
In other words, there are Mudrā that are primarily
utilised within the context of Haṭha Yoga and there are
Mudrā that are utilised within the context of Rāja Yoga.
Within these two viewpoints, there are also those Mudrā
that can be applied in either context, depending on the
Saṃkalpa and Bhāvana employed by the practitioner.
