Poornima and Amavasya in Breath

To understand the process of breathing along with the meaning and philosophy behind it essential for any yogi. When one breaths in, Pran enters Sun because of absence of Moon form Apaan its called Krishna paksha or night of waning moon. Moon starts giving away its piyush varshini kala and dharma of this kala is Apyayan. By the time it reaches 15th tuti (outside world it can be compared to Panchadashi, 15th night ), offering its kalas one by one, its kala expansion stops. The point where this kala expansions stops, is called Dwadashaant. This place is also a place of strengthening Panchadashi. Because of depletion of the kala expansion, the moon merges into the Sun. It is essential for a middle yogi to experience it while taking breath. 

The above mentioned point is the point of end of Prana and start of Apana and is known as sandhi sthal. One inhale and exhale represents one day in which it travels 36 fingers while inhaling and 36 fingers while exhaling and thus total length of 72 fingers is achieved. This distance of 72 fingers is divided in two parts of 15 tuti each. Though one Ahoratra is of 32 tuti, but two tutis are represented as 1/2 each in the place of Heart and Dwadashaant and they become the facilitator for combining of day-form Krishna-paksh and night form shukla paksh. Thus, they are known as Paksh sandhi (as per Hindu Calendar, 15 days represent one Paksh).

The first half of this half tuti is resting place of no-moon-night or amaavasya. Because of entry of Apan-form Moon in to the Pran-form -Sun,  its called Amavasya tutyaardh(half tuti). In similar way when the pran-hamsa reaches its resting space, when Shukla tattva arises, then coolness of Apaan-form-moon starts spreading. This half tuti is called Pratipada or prathama of first day-night.  

While in Kumbhak some time this smooth flow gets hindered, one might do coughing, as a result the natural division of pran and apan gets disturbed. This momentary lapse in pranachar is called Rin and same thing in exhaling side is called Ghan. Rin causes reduction in tithis and Ghan causes increase of tithis in our Hindi calendars. 

As per Jyotish Shastra, in Amavasya eclipse of the Sun takes place while in Poornima eclipse of the Moon takes place. Similar thing happens in our breath too. During inhalation at the time of lapse of tithi, due to higher flow of pran it enters into Pratipada or Prathama and Solar eclipse take place at this very point. Here Moon enters into Sun. At this point Rahu starts drinking the nectar of moon. This chance of nectar drinking represents eclipse state. In this talk of eclipse Moon(Prameya) and Rahu (Pramata) are not able to merge but only able to cover or overlap, thus Apan (state of Moon merged in Sun) drinks the nectar. This is the period of eclipse. That is why this time of equanimity of the two is called Punyakaal. It provides great fruit to the yogis and sadhaks both.

After this in the same flow, entry of Pran in the heart, Sun of the chit keeps fulfilling the Apan-Moon till 15th tuti Poornima arises. After this comes Paksh-Sandhi(change over space). Eclipse occurs and this time is for realization of the sankalp. Thus outer month movement is represented inwardly in our breath...................Tantrasaar.

Hope readers will surely understand some practical tips from above if not whole at start. With practice one will realize the whole with Her grace...............Shaktanand.
