The Keys of Introspection / The Beginning

One takes interest in things beyond ordinary sense perception only when one realizes that there is no intrinsic value in the unlimited manifestations of the combinations of tangible elements - no value, because they are all temporary.

Only the keys of introspection open the doors to such contemplation. Of course, the journey of enlightenment doesn't end here; there are still many more egoistic barriers to destroy and cross before we accept and harmonize ourselves with the eternal truths. But still, the beginning is always an important milestone, for there is no end before a beginning.

ye hi saṁsparśa-jā bhogā
duḥkha-yonaya eva te
ādy-antavantaḥ kaunteya
na teṣu ramate budhaḥ

Translation: 

An intelligent person does not take part in the sources of misery, which are due to contact with the material senses. O son of Kuntī, such pleasures have a beginning and an end, and so the wise man does not delight in them.
