There are many qualities of what is defined as passion which can be experienced. Though this term is habitually confused with the emotional flame with a transient, nonenduring nature, true passion has nothing to do with it.
Indeed, while what we commonly know as passion is often an emotional expression, the nature of the true passion resides in the spiritual sphere and comforms itself with the sacred, such as prayer, expression of heart, and real faith (so, once more, not what is commonly recognized under the name of faith).
When we speak about passion in this way, at this degree, we refer to a particular form of desire that leads a human being to the higher sphere of Love and Will of Fusion.
The true Passion, when it manifests itself, offers to who experiences it, the possibility of a yearning towards the object of desire, a yearning of a such degree and intensity which can become a real possibility of transcendence.
Evidently, the object of desire mentioned above can’t be something of the material, namely something that solicits our illusory personality, because in this case, it would only be a strong emotional impulse.
Just to give an example: when the object of desire is represented from a high ideal, from Love in its deepest and most elevated meaning, and when the desire achieves the degree and characteristic of a real request and will for Unity, then the nature of the real Passion arises, and it leads a human to overcome all his limits in order to annul the distance to the desired aim.
This is the passion that leads a human to scorch within himself, and through this inner flame transcend every separation in a neverending path, because the Real Passion hasn’t any limit: when the True Passion arises, this is the “real miracle”.
Thus, in every esoteric teaching, it is asked to establish an aim, in order to feed this inner fire.
