Here is a translation of verse 24 from Vigyan Bhairav Tantra
"Paradevi, whose nature is visarga, or creation, manifests as the upward prana and the downward apana. By fixing the mind at the two points of generation (of prana and apana), the state of fullness results.The Sanskrit word for Void is "Shoonya". The above verse however refers to the state (स्थितिः) of fullness (भारिता). Both void state and the state of fullness are an experience of the mind. A certain meditation technique can lead to the experience of void while another can lead to the experience of fullness. Techniques which involve the use of Prana or the life force yield a feeling of fullness.
What are the two points in the above verse. They are easy to understand under the guidance of a meditation master like Gurudev Sri Sri Ravishankar. Understanding the practical aspect of the verse provides an invaluable tool to feel content when the mind is bothered by a sense of lack. Should a person undergoing depression resort to fullness centric meditation technique? Psychologists and researchers will surely study different classes of meditation in the coming decades.
