During the 1990s, Vijay Kumar and his 'Oneness Movement' developed a series of meditation and wellness programs for the Indian market. In around 2014, the Oneness organization launched another series of programs designed to appeal to westerners. In 2017, NKV Krishna and Preetha Krishna merged the Oneness organisation with their own One World Academy to form 'O&O Academy'.These programs were aimed at westerners, and developed with the help of American wellness coach, Tony Robbins. During 2019, NKV Krishna and Preetha Krishna published a book together, called The Four Sacred Secrets, writing under the names 'Krishnaji' and 'Preethaji'.
