Om Namo Bhagavate Vāsudevāya
The kuṇḍalini has two channels on the left and right sides of the spine called the Iḍā and the Piṇgalā. The prāṇa enters these channels through the breath and an analysis of the breath gives an indication of the strength of the prāṇa. The breath/prāṇa is an indicator of the vāyu tattva, which is linked to the transit of the Moon in the nakṣatras.
During the Sun’s transit from the Uttarāyana to Āsāḍha Pūrṇimā (the full moon of the month of Āsāḍha), Deveśa Śripati (Lord Nārāyaṇa) retires to his Śeṣa śajyā (bed) to rest and sleep. Soon, one by one, the Gandharvas, the Goddesses and the Deva Mothers retire to their respective bedrooms. Pulastya Muni, upon Maharṣi Nārada’s request, gives a detailed description of the resting procedure of the gods starting from Lord Janārdana, in the Vāmana Purāṇa.
