prapya punya-kritam lokan
usitva sasvatih samah
sucinam srimatam gehe
"The unsuccessful yogi, after many, many years of enjoyment on the planets of the pious living entities, is born into a family of righteous people,with good intentions."
From this sloka Sri Krishna gives assurance of His support to the person, who has started yoga sincerely, in this life as well as in his ensuing births. A person has started yoga in all sincerity. Due to pull of desire in others like the pleasures in heaven or in Chandra loka or Kubera loka, he discontinues yoga and aspires for these inferior pleasures. At the right time, here after death of the person, the Lord ensures the person attains the pleasures he wanted. Punya kritam lokan = the worlds destined for those who have done punya, prapya = attains. This person is dispatched to the loka reserved for those who have done great punya; even though this person might not have performed so much punya to deserve that loka, but as he has begun yoga sincerely, he is granted that position. Sasvata sama = for long time, usitva = live there. Normally, for those who have done punya, these loka might be available for living till the punya account has balance and after exhausting all punya, all those persons are sent back to be born as whatever their karma is destined. But, this person, who has started the yoga and discontinued half way, is sent to these loka, reserved for all those who have performed great deeds. Not only that. This person can spend time for much, much longer times. Normally, it is human nature to long for something we do not have. As long as that is not had, this longing for that may be hurting us. But, once we get that and we enjoy its possession, then we will certainly feel that why we bothered the Lord for this small and inferior pleasure. We will then feel that we should continue to practice yoga and be loyal to the Lord. Detachment will creep in at that time and we will start thinking these inferior pleasures are enough. He will then be made to be born in a place where the surroundings will be conducive to restart the yoga from the point where he had discontinued in the previous birth. Yoga brashta = he who has slipped from or discontinued yoga, abhijayate = is well born in, sucinam = well intentioned, srimatham = of good character, gehe = houses. So this person, who sincerely started yoga, but has discontinued for variety of reasons, gets the desired pleasures, of inferior nature, in this or other lokas meant for noble souls, and after he is satisfied and says enough, he is made to be born in a house of families of good character and with good intentions [ to stimulate this person again in yoga]. The sloka says that this person is born in such families; but actually, it is the Lord, Who decides this course of destiny. Born in such families, this person is able to continue yoga from where he discontinued in his previous birth.
