The Rising of the Breath of Shiva with Commentary

In the beginning, the Moon rules the bright fortnight, and the Sun indeed rules the dark.
Starting from the first day, they are said to rise for three days each. || 62 ||

In the bright fortnight Shukla Paksha: the waxing phase of the moon, the breath of the Moon the left nostril flows first, and in the dark fortnight Krishna Paksha: the waning phase, the breath of the Sun the right nostril flows first. Starting from the first day of the lunar month, the breath of the Moon and the Sun remains dominant for three days each, alternating in that order. || 62 ||

The Moon and Sun are known to flow for two and a half ghatikas each in the bright and dark phases.
In a single day, they flow for sixty ghatikas in succession. || 63 ||

Furthermore, for two and a half ghatikas a traditional unit of time equal to 24 minutes; 2.5 ghatikas equals one hour the Moon flows in the bright fortnight, and for two and a half ghatikas the Sun flows in the dark fortnight, continuing for the full sixty ghatikas of a day. This means that both breaths complete twenty-four cycles each in a day. || 63 ||

Within those ghatikas, one should identify the five elements.
They are said to flow from the first day; one should avoid the opposite. || 64 ||

Within each of those two-and-a-half-ghatika periods, the five elements Tattvas: Earth, Water, Fire, Air, and Ether are said to manifest. If the flow is opposite to what is prescribed for the days starting from the first lunar day—meaning if the Sun breath flows during the Moon's time or the Moon breath during the Sun's time—one should avoid important actions, as it is considered inauspicious. || 64 ||

In the bright fortnight it should be the left, and in the dark fortnight the right.
The yogi, with a focused mind, should know this before the first lunar day begins. || 65 ||

Starting from the first day of the bright fortnight, the left nadi Ida, associated with the moon should flow first, and in the dark fortnight, the right nadi Pingala, associated with the sun should flow first. A yogi should recognize this with a concentrated heart. || 65 ||

Restrain the Moon during the night, and restrain the Sun during the day.
One who is thus constantly engaged in practice is truly a yogi; of this there is no doubt. || 66 ||
