Acharya Prashant addresses a question regarding the absence of concepts like chakras and Kundalini in the main Upanishads, despite their prevalence in modern spirituality. He explains that while the Upanishads do mention 'nadis' (energy channels), they do not talk about chakras or Kundalini. These concepts first appeared in Buddhist texts around the 8th century and entered Hindu scriptures around the 11th century, gaining wider acceptance around the 16th century. This entire Shakta tradition is relatively new and not central to the core of Sanatana Dharma. Despite its recent origin, the speaker affirms the importance of the message within Kundalini Yoga. He clarifies that it is a symbolic representation of the journey of consciousness. Ordinarily, human consciousness resides at its lowest possible level. This state is depicted as a coiled snake, the Kundalini, resting at the 'Muladhara' (root chakra), which literally means the lowest place, located at the base of the spine. The various chakras—Muladhara, Svadhisthana, Manipura, Anahata, Vishuddha, Ajna, and finally Sahasrara—are names for different levels or heights of consciousness. The entire spiritual practice (sadhana) is aimed at the upward journey of this consciousness, from the lowest to the highest chakra. The speaker warns against literal interpretations. The journey is of consciousness, not a physical snake moving up the spine. The body and its parts are used merely as an illustration or a scale to explain this inner journey. People often get confused and think something is physically happening in their navel, heart, or throat, but these are misinterpretations. The entire process is about consciousness. Forgetting that the journey is of consciousness and not the body leads to confusion. The speaker explains that Tantra, from which these practices originate, was developed for those who were not inclined towards the path of knowledge and were more body-identified. Therefore, it used symbols and illustrations related to the body to explain spiritual concepts. The goal of all sadhana is the upward movement of consciousness, and this is what Kundalini Yoga signifies.
