Article XVII: Purifying the Mind and Life

To purify the mind, one must be non-attached and devoid of desire. Only after this purification and control, can one reach enlightenment. One can be freed from desire by orienting all action toward the Divine. Selfless action and doing good for the sake of doing good is the way to peace. If one believes in a personal God, like Krishna or Shiva, then offer the fruits of your actions to the Lord. Otherwise, simply act righteously for the sake of righteousness, and do not be attached to the results of the actions. Simply, be a blissful witness regardless of the results. Focus on the Brahman within to guide your life to be selfless and righteous.

Amritabindu Upanishad
1: The mind is chiefly spoken of as of two kinds, pure and impure. The impure mind is that which is possessed of desire, and the pure mind is that which is devoid of desire.
2: It is indeed the mind that is the cause of men's bondage and liberation. The mind that is attached to sense-objects leads to bondage, while dissociated from sense-objects it tends to lead to liberation. So they (the wise) think.
3: Since liberation is predicated of the mind devoid of desire for sense-objects, therefore, the mind should always be made free of such desire, by the seeker after liberation.
4: When the mind, with its attachment for sense-objects annihilated, is fully controlled within the heart and thus realizes its own essence, then that Supreme State (is gained).
5: The mind should be controlled to that extent in which it gets merged in the heart. This is Jnana (realization) and this is Dhyana (meditation) also, all else is argumentation and verbiage.
6: (The Supreme State) is neither to be thought of (as being something external and pleasing to the mind), nor unworthy to be thought of (as something unpleasant to the mind); nor is It to be thought of (as being of the form of sense-pleasure), but to be thought of (as the essence of the ever-manifest, eternal, supreme Bliss Itself); that Brahman, which is free from all partiality is attained in that state.
7: One should duly practice concentration on Om (first) through the means of its letters, then meditate on Om without regard to its letters. Finally, on the realization with this latter form of meditation on Om, the idea of the non- entity is attained as entity.
8: That alone is Brahman, without component parts, without doubt, and without taint. Realizing "I am that Brahman," one becomes the immutable Brahman.
9: (Brahman is) without doubt, endless, beyond reason and analogy, beyond all proofs and causeless knowing which the wise one becomes free.
10: The highest Truth is that (pure consciousness) which realizes, "There is neither control of the mind, nor its coming into play," "Neither am I bound, nor am I a worshipper, neither am I a seeker after liberation, nor one who has attained liberation."
