Nectar from the moon from the book "The mirror of yoga" by Richard Freeman

One of the meanings of the word rasa is "relationship," referring to the
aesthetic pleasure coming from interfacing with another. The different rasas, or
flavors, of love correspond to a strong feeling of luminous, intense, pleasurable
joy, which seems to come from what is called the root of the palate. The
palate is located approximately at the pituitary gland, and is felt by releasing
the soft palate as if subtly smiling. The quintessence of all of the rasas
is called amrta, or nectar. its primary quality is compassion. The nectar
drips down through the petals of the sahasrara, the thousand-petaled lotus,
to the reservoir just above the root of the palate called the moon. When mula bandha
or yoni mudra, is done well it causes nectar to drip from this moon
and that nectar fills all of the nadis, transforming one’s body and every sensation
the experience of consciousness and joy.
