The Acintya Bheda Abheda philosophy is similar to Dvaitadvaita (differential monism). In this philosophy, Brahman is not just impersonal, but also personal. That Brahman is Supreme Personality of Godhead, though on first stage of realization (by process called jnana) of Absolute Truth, He is realized as impersonal Brahman, then as personal Brahman having eternal Vaikuntha abode (also known as Brahmalokah sanatana), then as Paramatma (by process of yoga-meditation on Supersoul, Vishnu-God in heart)—Vishnu (Narayana, also in everyone's heart) who has many abodes known as Vishnulokas (Vaikunthalokas), and finally (Absolute Truth is realized by bhakti) as Bhagavan, Supreme Personality of Godhead, who is source of both Paramatma and Brahman (personal, impersonal, or both).
