By Swami Harshananda
Samanu literally means ‘with mantra’.
‘Manu’ means a mantra. Works on Haṭhayoga describe various processes of prāṇāyāma for nāḍīśuddhi. Very often, certain bāḍīśuddhi like yam, ram and ṭham are associated with the different stages of these prāṇāyāmas. Hence they are called ‘samanu’.Gheranda Samhitā 5.36-45</ref> The actual processes have to be learnt personally from expert teachers.
