यं हि न व्यथयन्त्येते पुरुषं पुरुषर्षभ | समदुःखसुखं धीरं सोऽमृतत्वाय कल्पते
yaṃ hi na vyathayantyete puruṣaṃ puruṣarṣabha . samaduḥkhasukhaṃ dhīraṃ so.amṛtatvāya kalpate
人々のうちの最たる者よ、これらのものが苦しめない人、苦楽を等しく見る賢者は、不死に適格である。
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.
自己を肉体と同一視する「デーハードヤーサ」（Dehadhyasa）が苦楽の原因です。不死なる、遍在するアートマンと自己を同一視するほど、苦楽などの対立する二元性（ドヴァンドヴァ）の影響を受けにくくなります。「ティティクシャー」（Titiksha）すなわち忍耐力は意志力を養い、ジュニャーナ・ヨーガの道を進む求道者にとって重要な資質の一つです。
-- 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)
