Bhagwad Gita - Post 79

Verse 37

Arjuna Uvaacha:

Ayatih shraddhayopeto

Yogaacchalitamaanasah;

Apraapya yogasamsiddhim

Kaam gatim krishna gacchati.

Arjuna said:

He who is unable to control himself though he has the faith, and whose mind wanders away from Yoga, what end does he meet, having failed to attain perfection in Yoga, O Krishna?

The journey toward God-realization begins with Shraddha (faith). Many sincere souls develop faith in the divine knowledge of the scriptures by virtue of the sanskara of their past lives, or the association of saints, or reversals in the world, etc. 

There can be many reasons that create the Shraddha required to begin the journey. However, if these aspirants do not put in the necessary effort and become ayatiḥ (lax), then the mind remains chalita (restless). 

Such aspirants are unable to complete the journey in this life. Arjuna enquires into the fate of such sadhakas.

Verse 38

Kacchinnobhayavibhrashtash

Cchinnaabhramiva nashyati;

Apratishtho mahaabaaho

Vimoodho brahmanah pathi.

Fallen from both, does he not perish like a rent cloud, support less, O mighty-armed (Krishna), deluded on the path of Brahman?

  

 Chinmaya writes, 

"In summer, mushroom-shaped floating castles of clouds arise from behind the mountains to peep into the valleys below. At the touch of some strong current of wind the mass takes to flight, leaving along its trail, small bits of fleecy cloudlets. Those little ones, torn away from the parental bulk, get knocked about and are at the mercy of every puff of breeze. 

Such summer cloudlets, aimlessly kicked about according to the whims and fancies of the winds, can never fulfil the expectations of the farmers, or the clamor of the thirsty. Unfulfilling themselves, they get tossed hither and thither without any haven for themselves. "LIKE THE RENT CLOUD," Arjuna asks, "will not the aspiring self in the seeker be forced to roam about and ultimately get lost in the vast theatre of the Universe?"

Dear All, 

Firstly, an aspirant having exclusively offered all activities unto the Supreme Lord without having performed any activities for attaining the heavenly spheres does not arrive there. 

Secondly failing to obtain success in yoga or the science of the individual consciousness attaining communion with the ultimate consciousness by dhyana or meditation one does not attain moksha or liberation from the material existence either. 

Thus, not qualified for both and deluded on the path leading to the Brahman or the spiritual substratum pervading all existence and atma tattva or realization of the soul. 

Arjuna here represents the world of Spiritual aspirants in all times, past and present, when he asks this question to Sri Krishna, 

Does such a one perish or does such a one escape death? 

Love.
