Acharya Prashant explains the concept of "Brahma-nishtha" or fixity in the Supreme Spirit, as mentioned by Ramana Maharshi. He begins by stating that Brahma, the Supreme Truth, is not an object of thought. Therefore, the idea of being devoted to Brahma does not make literal sense, as one cannot be devoted to something that is not a 'thing' in the usual sense. We are typically devoted to various objects, people, or ideas, but Brahma is not one of them. He clarifies that "Brahma-nishtha" should be understood not as devotion to an object, but as a method or a tool. It serves as a touchstone or a gold standard to check all our other miscellaneous devotions. We are devoted to countless things, and Brahma-nishtha is the process of testing these devotions. Using the example of being devoted to a towel, he explains that one must test this devotion against the attributes of Brahma. The great masters have described Brahma as formless, timeless (never born and never disappearing), without location, without support, and without color. When the towel is examined against these attributes, it is clear that it has a form, a beginning and an end, a location, and a color. This reveals that the devotion to the towel is misplaced and harmful. Therefore, Brahma-nishtha is a tool for discrimination (vivechana) that helps us assess our various devotions and discover that most of what we consider important actually holds very little value and does not deserve our devotion. The masters teach that only two things are worthy of devotion: either the formless Brahma itself, or a form of Brahma (like a Guru) that leads one to the formless. In reality, these two are one. Except for these, nothing else is of any real value or deserves our attention and devotion. This process of using the concept of Brahma to filter out all unworthy devotions is the true meaning of Brahma-nishtha.
