यं हि न व्यथयन्त्येते पुरुषं पुरुषर्षभ | समदुःखसुखं धीरं सोऽमृतत्वाय कल्पते
yaṃ hi na vyathayantyete puruṣaṃ puruṣarṣabha . samaduḥkhasukhaṃ dhīraṃ so.amṛtatvāya kalpate
人中之雄啊（阿周那），那些不能折磨的人，即苦乐平等、心境坚定之人，他堪得不朽。
O (Arjuna, who are) foremost among men, verily, the person whom these do not torment, the wise man to whom sorrow and happhiness are the same he is fit for Immortality.
将真我（Self）与身体认同（Dehadhyasa）是苦乐的根源。越能将自己与不朽、遍在的真我认同，就越少受二元对立（Dvandvas，如苦乐等）的影响。“提提克沙”（Titiksha，忍耐力）能培养意志力。在苦乐、寒暑中保持平静的忍耐，是智瑜伽（Jnana Yoga）修行者必备的品质之一，也是“沙特桑帕特”（Shatsampat，六种美德）之一。它是正知的前提。提提克沙本身不能带来解脱（Moksha），但若与辨别力和无欲结合，它就成为获得不朽或真我知识的途径。
-- Dehadhyasa or identification of the Self with the body is the cause of pleasure and pain. The more you are able to identify yourself with the immortal? allpervading Self? the less will you be affected by the pairs of opposites (Dvandvas? pleasure and pain? etc.)Titiksha or the power of endurance develops the willpower. Calm endurance in pleasure and pain? and heat and cold is one of the alifications of an aspirant on the path of Jnana Yoga. It is one of the Shatsampat or sixfold virtues. It is a condition of right knowledge. Titiksha by itself cannot give you Moksha or liberation? but still? when coupled with discrimination and dispassion? it becomes a means to the attainment of Immortality or knowledge of the Self. (Cf.XVII.53)
