Identity (of the self) is a fundamental concept that one develops about oneself that evolves over time. A fixed identity composed of name, relationships, and belongings keeps one locked in small self.
How can one proactively evolve or transform one’s identity? First step would be to locate and unfreeze the current identity. Research has shown that there is a part in the brain that is responsible for one’s memory and identity. That part is hippocampus (seahorse-shaped) in the middle of the brain. To transform one’s identity is to change the flexibility of that part of the brain.
Yagyas such as AtiRudraAbhishekam when done properly are a great way for self-transformation. Ashwamdetha yagyas are another way to achieve that. Coming from the Vedic tradition, the Ashvamedha is a ritual used by great Indian kings to expand their imperial sovereignty. A stallion would be released to wander for a period of one year. Whatever area the horse would cover in a year, unless challenged, would belong to the king. Then the horse is sacrificed.
There are two ways to explain the change in identity: Imagination and Transcendence.
Ashwamedha yagyas lets the king’s horse roam freely to as far as it can. Similarly, if the mind is free to imagine itself in the most expansive terms, it could be the broadening or expansion of identity. All of that territory becomes the mind’s. That is the way to understand it from an object-referral method.
Ashwamedha yagyas is also seen as the sacrificing the horse. Sacrificing the specificity-oriented mind to give way to a wholeness-oriented self, is the self-referral way of explaining self-transformation. That identity of specificity has to be erased and identity of wholeness has to settle in.
Transcendence is the forgetting of specificity and stepping into wholeness. Transcendental Meditation is an effective and proven method for self-transcendence. While both are complementary concepts, Self-transformation through transcendence may be more desirable than self-expansion through imagination.
