4.39. He, who has faith, gains knowledge, if he is solely intending upon it and has his sense-organs well-controlled; having gained the knowledge, he attains, before long, the Peace Supreme.
Shri Purohit Swami
4.39 He who is full of faith attains wisdom, and he too who can control his senses, having attained that wisdom, he shall ere long attain Supreme Peace.
Sri Abhinav Gupta
4.39 See Comment under 4.40
4.39 After attaining knowledge through instruction in the manner described, he must have firm faith in it and the possibility of its development into ripe knowledge. He must be intent on it, i.e., his mind must be focussed thereupon. He must control his senses and keep them away from all their objects. Soon will he then reach the aforesaid state of maturity and obtain knowledge. Soon after attaining such kind of knowledge, he will reach supreme peace, i.e., he attains the supreme Nirvana (realisation of the self).
4.39 Sraddhavan, the man who has faith; labhate, attains; jnanam, Knowledge. Even when one has faith, he may be indolent. Therefore the Lord says, tatparah, who is diligent, steadfast in the service of the teacher, etc., which are the means of attaining Knowledge. Even when one has faith and is diligent, one may not have control over the organs. Hence the Lord says, samyata-indriyah, who has control over the organs-he whose organs (indriyani) have been withdrawn (samyata) from objects. He who is such, who is full of faith, diligent, and has control over the organs, does surely attain Knowledge. However, prostrations etc., which are external, are not invariably fruitful, for there is scope for dissimulation faith etc. But this is not so in the case of one possessing faith etc. Hence they are the unfailing means of acquiring Knowledge. What, again, will result from gaining Knowledge? This is being answered: Labdhva, achieving; jnanam, Knowledge; adhigacchati, one attains; acirena, soon indeed; param, supreme; santim, Peace, supreme detachment called Liberation. That Liberation soon follows from full Knowledge is a fact well ascertained from all the scriptures and reasoning. One should not entertain any doubt in this matter. For doubt is the most vicious thing. Why? The answer is being stated:
4.39 He who has faith, who is intent on it, and who has mastered his senses, attains knowledge. Having attained knowledge, he goes soon to supreme peace.
4.39 The man who has faith, is diligent and has control over the organs, attains Knowledge. Achieving Knowledge, one soon attains supreme Peace.
4.39 The man who is full of faith, who is devoted to it, and who has subdued the senses obtains (this) knowledge; and having obtained the knowledge he attains at once to the supreme peace.
4.39 श्रद्धावान् the man of faith? लभते obtains? ज्ञानम् knowledge? तत्परः devoted? संयतेन्द्रियः who has subdued the senses? ज्ञानम् knowledge? लब्ध्वा having obtained? पराम् supreme? शान्तिम् to peace? अचिरेण at once? अधिगच्छति attains.Commentary He who is full of faith? who constantly serves his Guru and hears his teachings? who has subdued the senses surely gets the knowledge and ickly attains the supreme peace or salvation (Moksha). All the above three alifications are indispensable for an aspirant if he wants to attain to the supreme peace of the Eternal ickly. One alifiaction alone will not suffice. (Cf.X.10?11)
