2I x. Sarna Vrtti Pra'f}Ziyama
I. Sarna means the same or identical, straight, entire, whole and
complete: also similarly or in the same manner.
- Vrtti means action, movement, function or operation, a course of
 conduct or method.
3· In Sarna Vrtti Pra1,1ayama, therefore, an attempt is made to
achieve uniformity in the duration of all the three processes of
breathing, namely, puraka or inhalation, kumbhaka or retention, and
rechaka or exhalation in any type of pra1,1ayama. If one lasts^5 seconds
so do the others.
4· This uniformity of 5 seconds should be maintained throughout all
the cycles of breathing in any type of Pranayama like Ujjay'i, Siirya
Bhedana, Na�n Sodhana, Sital'i and so on.
·Caution
5· In the beginning Sarna Vrtti Pra1,1ayama should be confined only
to inhalation (puraka) and exhalation (rechaka).- First, achieve uniformity of length of time in puraka and rechaka
 then only attempt antara kumbhaka (retention of breath after full
 inhalation).
 7· Start the antara kumbhaka gradually. In the beginning, the ratio
 of time for piiraka, antara kumbhaka and rechaka should be kept at
 I : t : I. Very slowly increase the proportions to I :! : I. After this is
 firmly established attempt I : � : I. Only after mastering this, increase
 the proportion of' antara kumbhaka so as to achieve the ratio of
 I : I : I.
 8. Do not attempt bahya kumbhaka (restraint of breath after full
 exhalation) until you have achieved the desired ratio of I : I : I in
 piiraka, antara kumbhaka and rechaka.
 9· If all air is expelled from the lungs, the vacuum inside and the
 atmospheric pressure outside will create a tremendous strain upon the
 lungs. Therefore, in the beginning, do not do both an tara kumbhaka and
 bahya kumbhaka together.
 Io. Practise antara kumbhaka and bahya kumbhaka separately or
 alternately. It is beneficial to practise kumbhakas first by interspersing
