There is no relative bodhicitta without absolute bodhicitta, and there is no absolute bodhicitta without relative bodhicitta.
The designations of “absolute”and “relative” can only be when the two are compared with each other.
In other words,
“Absolute” only exists in relation to “relative”
which means that absolute bodhicitta is relative too.
But really, the term “bodhicitta” refers to two different things. Relative bodhicitta refers to the altruistic mind, while absolute bodhicitta refers to the mind which directly perceives emptiness.
Frankly, I don’t know why the same word is used for two different things. One could perceive emptiness yet never care about anyone else, couldn’t they?
