So what is the nature of Bodhicitta? Bodhicitta is divided into two, awareness mind and realised mind. Awareness means to remain in tranquility. It also means having eliminated our selfishness and the wish for self liberation. Realised means having arrived or achieved the mind that work only for the benefits of all sentient beings. Therefore, if we can eliminate our selfishness and work only for the benefits of all sentient beings; at the same time, generate the wish for the good of all sentient beings then this is called the realised mind.
