This explains the Possuk: סה בְיָּדוֹ הַבָּא מִּן וַיִּקַח
Link between the Neshomoh and the body, which is why it is through smelling that one is awoken from a faint. It is brought down in the Zohar that the scent that one inhales via the nose is the essence of vitality, and there are two levels, which are the two nostrils referred to in the Zohar as the ‘Pardashka’ of the nose, the right nostril and the left nostril. Also, in smelling itself there are two levels: There is smelling good food, like the smell of the animal sacrifices, which is smelt through the right nostril; and then there is pure smell, like the smell of the Ketores incense offering—particularly the Ketores from Yom Kippur which is pure scent which is smelt through the left nostril. This pure scent reaches the deepest part of the Neshomoh referred to as ‘Yechidah’ or the Neshomoh of the Neshomoh and can be reached via smelling through the left nostril. (The left nostril is also more Makif related, associated with Moshiach and Moreh Vadoin, also associated with Teshuvah).
Left nostril: The Zohar says that through the right nostril one draws in life, but through the left nostril one draws in life of life. And it explains that the nose is the gate for the essence of intellect because it is there that there is a connection and binding with the essence of the Neshomoh. But there are two levels of Hamshocha from there: life and life of life, Life is in the right nostril... the general revelation of the vitality to vitalise a person’s body... which is the breathing which shows life ... the vitality from the brain comes into the heart in the blood and the heart sends the blood and the vitality to each and every limb and this is the internal vitality.... However, the left nostril is the life of life, which is Mamosh from the essence of the Neshomoh, in the essence of its connection with the essence of the intellect.
