“ pUrNatvAt purushaha “ - when a person attains perfection, completeness, entireness is called Purusha.
Rishis, with their severe penance, could see the virat purusha who is Omnipresent, Omniscient and Omnipotent. They praised the Purusha and it's the famous Purusha suktam.
Vishnu means Omnipresent, so some worshipped purusha as Vishnu. Some worshipped purusha as Siva as he is auspicious and giver of all goodness.
In the "Purusha Suktam," a section of the Rigveda, it is stated thus:
cha̠ndramā̠ mana̍sō jā̠taḥ ।
chakṣō̠-ssūryō̍ ajāyata ।
mukhā̠dindra̍śchā̠gniścha̍ । prā̠ṇādvā̠yura̍jāyata ॥
nAbhyA AsIdantariksham......."
While describing the *Virat Swarupa* (the Cosmic Form—"He has a thousand heads, a thousand eyes, a thousand feet..."), the sages revealed that the sky originated from His "navel ".
The Taittiriya Upanishad states thus:
AkaSAt vAyuh, vAyOragnih,
agnErapah, adbhyah prithivi,
prithivyAt aushadhIyah, aushadhIbhyO annam, annAt purushah."
This translates to: " From Sky comes Air; from Air, Fire; from Fire, Water; from Water, Earth; from Earth, medicinal plants; from these, Food; and from Food, living beings." If it is indeed through food that living beings (we ourselves) sustain their existence, then one must conclude that the ultimate source of our survival is Sky.
Now, if we examine these two points together, what becomes clear is that the "navel" is the very source of our existence; it signifies that all the essentials required for living beings—namely air, water, fire, and food—emanate from the "Lord's" navel. It implies that creation itself began from that very spot. What a profound concept! It is, therefore, reasonable to assume that our ancestors accorded such immense significance to the "navel" for this very reason.
Grasping this profound truth, our ancestors likely established the tradition of enclosing a newborn's "umbilical cord" within an amulet and tying it around the infant's waist. Furthermore, they may well have imparted other vital insights—such as how and for what purposes this umbilical cord could be utilized. However, due to centuries of foreign rule, such remarkable wisdom may have unfortunately faded into obscurity.
A few days ago, we came across a post suggesting that gently massaging an oil—prepared using specific herbal ingredients—around or directly upon the navel can alleviate or cure a wide range of ailments. It is highly probable that all such information is already documented within our ancient Ayurvedic texts. Let us hope that, even now, due attention and focus will be directed toward these invaluable insights. That is why this system of medicine was named "Ayurveda," thereby according it the same reverence reserved for the Vedas.
Let us hope that the Indian Sanatana Dharma and society will be preserved.
