The only one I have is from BSST Brahmana and Vaisnava (sorry no other sources):
The three features of the nondual Absolute Truth are endowed with energies. Bhagavan is the supreme controller of all illusory and spiritual energies, Paramatma, as the indwelling Supersoul, is the Lord of most of the illusory energy and a portion of the spiritual energy, while Brahman is pure consciousness in isolation from all qualities that are known in terms of the Supreme Lord's energies. As an object is perceived differently by different senses, so the Absolute Truth, although one, appears in three forms. These three, however, should not be considered actually different. It has already been described that the possessor of the material and spiritual energies cannot be perceived simply through impersonal knowledge. Although through the combined features of the sat and cit aspects the Supreme Lord's mastery over the illusory enery and the variegatedness of Vaikuntha is found, these features do not reveal the fullness of the expanded pastimes of the energy and the energetic. The Supreme Lord fully manifests only through the combination of the sat, cit, and ananda aspects.
and BSST commentary on Sri Siksastaka by BVT
Learned scholars of the absolute truth have described the supreme non-dual substance (advaya jnana vastu) in three different stages. When that non-dual substance is realised exclusively by knowledge, or in others words through the function of the cit potency, it is referred to as 'Brahma'. When realised through the combined functions of the sat and cit potencies, it is referred to as 'Paramatma', and when realised through the functions of all potencies-sat, cit, and ananda-that supreme truth is referred to as 'Bhagavan'.
