Daily Reading: Bhagvad Gita As it is- Page-58

Bg 2.14

mātrā-sparśās tu kaunteya
śītoṣṇa-sukha-duḥkha-dāḥ
āgamāpāyino ’nityās
tāṁs titikṣasva bhārata

Translation: 

O son of Kuntī, the nonpermanent appearance of happiness and distress, and their disappearance in due course, are like the appearance and disappearance of winter and summer seasons. They arise from sense perception, O scion of Bharata, and one must learn to tolerate them without being disturbed.

Purport: 

In the proper discharge of duty, one has to learn to tolerate nonpermanent appearances and disappearances of happiness and distress. According to Vedic injunction, one has to take his bath early in the morning even during the month of Māgha (January-February). It is very cold at that time, but in spite of that a man who abides by the religious principles does not hesitate to take his bath. Similarly, a woman does not hesitate to cook in the kitchen in the months of May and June, the hottest part of the summer season. One has to execute his duty in spite of climatic inconveniences. Similarly, to fight is the religious principle of the kṣatriyas, and although one has to fight with some friend or relative, one should not deviate from his prescribed duty. One has to follow the prescribed rules and regulations of religious principles in order to rise up to the platform of knowledge, because by knowledge and devotion only can one liberate himself from the clutches of māyā (illusion).

The two different names of address given to Arjuna are also significant. To address him as Kaunteya signifies his great blood relations from his mother’s side; and to address him as Bhārata signifies his greatness from his father’s side. From both sides he is supposed to have a great heritage. A great heritage brings responsibility in the matter of proper discharge of duties; therefore, he cannot avoid fighting.

Bg 2.15

yaṁ hi na vyathayanty ete
puruṣaṁ puruṣarṣabha
sama-duḥkha-sukhaṁ dhīraṁ
so ’mṛtatvāya kalpate

Translation: 

O best among men [Arjuna], the person who is not disturbed by happiness and distress and is steady in both is certainly eligible for liberation.

Purport: 

Anyone who is steady in his determination for the advanced stage of spiritual realization and can equally tolerate the onslaughts of distress and happiness is certainly a person eligible for liberation. In the varṇāśrama institution, the fourth stage of life, namely the renounced order (sannyāsa), is a painstaking situation. But one who is serious about making his life perfect surely adopts the sannyāsa order of life in spite of all difficulties. The difficulties usually arise from having to sever family relationships, to give up the connection of wife and children. But if anyone is able to tolerate such difficulties, surely his path to spiritual realization is complete. Similarly, in Arjuna’s discharge of duties as a kṣatriya, he is advised to persevere, even if it is difficult to fight with his family members or similarly beloved persons. Lord Caitanya took sannyāsa at the age of twenty-four, and His dependents, young wife as well as old mother, had no one else to look after them. Yet for a higher cause He took sannyāsa and was steady in the discharge of higher duties. That is the way of achieving liberation from material bondage.
