The word ātmā also means "to endeavor." In every practice there is some endeavor, and the ultimate endeavor is the endeavor to reach the highest perfectional stage of devotional service. In Śrīmad-Bhāgavatam (1.5.18) it is stated that one should try to attain the highest goal, which cannot be attained either in the higher or lower planetary systems. The idea is that material happiness and misery are available in all planetary systems in the course of time, but the highest achievement, devotional service, cannot be attained anywhere without endeavor. Therefore in the Bṛhan-nāradīya Purāṇa it is said that one who is serious about understanding the highest perfectional stage of devotional service can become successful in everything simply by his endeavor. One cannot attain the highest perfectional stage of devotional service without personal endeavor. As Kṛṣṇa states in Bhagavad-gītā:
- teṣāṁ satata-yuktānāṁ
- bhajatāṁ prīti-pūrvakam
- dadāmi buddhi-yogaṁ taṁ
- yena mām upayānti te
