A practitioner experiences the nature of Brahma (the creative power), the power of material diversity and countless channels, the connection between them. An ordinary person gets entangled in these material connections, while the yogi “sneak out” of them. In his heart he comprehends the nature of Nārāyaṇa. Nara means “a man”, that implies our connections with people, human attachments, these are emotional connections with people too. When we are “released” by a variety of bindings, the knot untied. Rudra is associated with liberation, with various experiences of the subtle level, with “spiritual ideas” and identification of oneself with them. That is, the idea of liberation is not liberation itself; thoughts of emptiness are not emptiness itself. There is a suitable definition in Russian Orthodoxy, I have come across, “falling into falsehood.” If a practitioner leaves clinging to such self-identifications, then he passes, frees this knots (granthis) and receives a living spiritual experience. This living realisation, associated with the sahasrāra cakra, is easier to experience in practice than to talk about it. Nevertheless, my experience shows that for full development you need a perfect guide, a Master. The gates to the sahasrāra open through the Guru-cakra that precedes it.
