Being in the present, is yoga.
The obstacles, or the difficult and challenging life experiences, that train and allow the mind to be in the present, is the yoga practice.
Being in the present, allows the mind to be free from unnecessary anticipation, projection, fear and worry upon coming in contact with obstacle, challenge, uncertainty, or the unknown, which is something very common in everyday life, particularly in this era where ignorance and egoism is predominant in everywhere.
That allows the mind to be free from unnecessary hesitation to take the chance to explore what is possible, in somewhere else other than this, as well as let it be, after doing one's best exploring some other alternatives or possibilities that are available or possible, upon coming in contact with something that is not possible right here, in this moment.
Things worked out in many ways that the mind never think of, without expectation, without trying to control everything to be the way that the mind thinks and desires how it should be.
Accepting or respecting the reality as it is, doesn't mean that one gives in to any obstacle, difficulty, or challenge, and stop trying or striving to reach one's destination or goal, but one can do one's best to seek some other alternatives or possibilities that are unknown to oneself, while being unaffected, undisturbed or undetermined by the existing obstacle, difficulty or challenge.
