cañcalaṁ hi manaḥ kṛṣṇa pramāthi balavad dṛḍham |
tasyāhaṁ nigrahaṁ manye vāyor iva suduṣkaram ||
(Śrīmad Bhagavad-gītā: 6.34)
“O Kṛṣṇa, because the mind is restless, agitating, powerful, and obstinate, I consider controlling it, like [trying to control] the wind, extremely difficult.”
ajñaś cāśraddadhānaś ca saṁśayātmā vinaśyati |
nāyaṁ loko’sti na paro na sukhaṁ saṁśayātmanaḥ ||
(Śrīmad Bhagavad-gītā: 4.40)
“One who is ignorant [i.e., devoid of knowledge of śāstra], devoid of śraddhā [as a result of observing differences of opinion about the meaning of śāstra], and doubtful [regarding whether something will actually lead to success] is ruined. Neither this world [i.e., any future prospect of well-being in this world], nor the next [i.e., any prospect of attaining a desirable afterlife], nor happiness [i.e., any present sense of satisfaction] exist for one who is doubtful.”
karmaṇy evādhikāras te mā phaleṣu kadācana |
mā karma-phala-hetur bhūr mā te saṅgo’stv akarmaṇi ||
(Śrīmad Bhagavad-gītā: 2.47)
“Your eligibility is only for karma, and never for [partaking of] the results. May you not be a cause of results of your karma [i.e., may you not perform karma out of desire for the results], and may you have no attachment to non-karma [i.e., non-performance of your karma, or, committing sin].”
yaṁ yaṁ vāpi smaran bhāvaṁ tyajaty ante kalevaram |
taṁ tam evaiti kaunteya sadā tad-bhāva-bhāvitaḥ ||
(Śrīmad Bhagavad-gītā: 8.6)
“O Kaunteya, whatever object one remembers as one leaves the body at death—exactly that one attains, [on account of] being constantly absorbed in thought of that.”
