Sri Aurobindo identifies three primary methods that are used to try to overcome the inequality caused by the dualities, the play of the Gunas and the limitations of the lower Nature as the seeker attempts to transition to the divine standpoint. These involve endurance, indifference and submission.
The power of endurance has been identified most closely with the stoic philosophical tradition, although it has been used universally within the framework of many spiritual, religious or philosophical traditions. This can be a very useful methodology for the evolving soul and, as Sri Aurobindo describes, it can have meritable results:
“Instead of seeking to protect itself from or to shun and escape the unpleasant impacts it may confront them and teach itself to suffer and to bear them with perseverance, with fortitude, an increasing equanimity or an austere or calm acceptance. This attitude, this discipline brings out three results, three powers of the soul in relation to things. First, it is found that what was before unbearable, becomes easy to endure; the scale of the power that meets the impact rises in degree; it needs a greater and greater force of it or of its protracted incidence to cause trouble, pain, grief, aversion or any other of the notes in the gamut of the unpleasant reactions. Secondly, it is found that the conscious nature divides itself into two parts, one of the normal mental and emotional nature in which the customary reactions continue to take place, another of the higher will and reason which observes and is not troubled or affected by the passion of this lower nature, does not accept it as its own, does not approve, sanction or participate. Then the lower nature begins to lose the force and power of its reactions, to submit to the suggestions of calm and strength from the higher reason and will, and gradually that calm and strength take possession of the mental and emotional, even of the sensational, vital and physical being. This brings the third power and result, the power by this endurance and mastery, this separation and rejection of the lower nature, to get rid of the normal reactions and even, if we will, to remould all our modes of experience by the strength of the spirit. This method is applied not only to the unpleasant, but also to the pleasant reactions; the soul refuses to give itself up to or be carried away by them; it endures with calm the impacts which bring joy and pleasure, refuses to be excited by them and replaces the joy and eager seeking of the mind after pleasant things by the calm of the spirit. It can be applied too to the thought-mind in a calm reception of knowledge and of limitations of knowledge which refuses to be carried away by the fascination of this attractive or repelled by dislike for that unaccustomed or unpalatable thought-suggestion and waits on the Truth with a detached observation which allows it to grow on the strong, disinterested, mastering will and reason. Thus the soul becomes gradually equal to all things, master of itself, adequate to meet the world with a strong front in the mind and an undisturbed serenity of the spirit.”
