We hear in many circles of the expression of oneness , especially in spiritual circles , but not necessarily exclusively. 

The Vedas has many things to say on the subject. 

In layman’s terms, oneness could be identified with anything from the oneness of a sports team employing skills to defeat opponents or, in more personal terms, the oneness two lovers may feel for each other .

The four main sampradayas of the Vedas , namely the Bramha , Laxmi , Rudra and Kumara sampradayas, whose main teachers are Mädhava acarya , Ramanuja acarya, Visnuswami and Nimbarkacarya , have a great deal to say on the topic , oneness is throughly analysed and is termed as  purified monism , specific monism, pure monism and  one and difference and finally inconceivable one and difference. 

The sanskrit term Pranaya means very intimate oneness with the interests , feelings, and emotions towards Divinity that are extremely prominently displayed and with extraordinary spiritual emotions, Rupa Goswami has an analysis of every single emotion and in his books describes pure unmotivated love .

The Sankacarya school of oneness with God’s impersonal energies are felt but to a much lesser degree than personality exchanges, and actually, the Sankacarya school illiminates     transcendental form , emotions, and intimate feelings towards Divinity .  The Sankacarya school appear not to  understand that  therapeutically , when emotions and feelings are exchanged in oneness with Krishna or His expansions , they become not a source  of difficulty but rather a source of ever increasing of bliss and love .
