The Perfection of Yoga
kaccin nobhaya-vibhraṣṭaś 
  chinnābhram iva naśyati 
  apratiṣṭho mahā-bāho 
  vimūḍho brāhmaṇaḥ pathi
“O mighty-armed Kṛṣṇa,” Arjuna continues, “does not such a man, being deviated from the path of Transcendence, perish like a riven cloud, with no position in any sphere?” (Bg. 6.38) When a cloud is torn apart by the wind, it does not mend back together again.
etan me saṁśayaṁ kṛṣṇa 
  chettum arhasy aśeṣataḥ 
  tvad-anyaḥ saṁśayasyāsya 
  chettā na hy upapadyate
“This is my doubt O Kṛṣṇa, and I ask You to dispel it completely. But for Yourself, no one is to be found who can destroy this doubt.” (Bg. 6.39) Arjuna is asking this question about the fate of the unsuccessful  yogī  so that in the future people would not be discouraged. By a  yogī , Arjuna is referring to the  haṭha-yogī ,  jñāna-yogī , and  bhakti-yogī ; it is not that meditation is the only form of  yoga . The meditator, the philosopher and the devotee are all to be considered  yogīs . Arjuna is questioning for all those who are attempting to become successful transcendentalists. And how does Śrī Kṛṣṇa answer him?
śrī bhagavān uvāca 
  pārtha naiveha nāmutra 
  vināśas tasya vidyate 
  na hi kalyāṇa-kṛt kaścid 
  durgatiṁ tata gacchati
