Bhagavad Gita sings:
श्रद्धावाँल्लभते ज्ञानं तत्परः संयतेन्द्रियः ।
ज्ञानं लब्ध्वा परां शान्तिमचिरेणाधिगच्छति ॥४-३९॥
śraddhāvānl labhate jñānam
jñānam labdhvā parām śāntim
“The worshipper of true faith who has subdued his senses attains to this knowledge and at the very moment (of attainment) he is rewarded with the benediction of supreme peace.”
For realization of God one needs to possess faith, determination, and restraint of the senses. If there is no intensely felt curiosity for the knowledge of God, even taking refuge in a seer will not bring it.
Also, mere faith is not enough. The worshipper’s effort may be feeble.Therefore, the determination to proceed resolutely along the prescribed way is a necessity. Along with this it is also necessary to restrain the senses.Realization of the Supreme God will not come easily to one who is not free from desire. So only a man who has faith, enthusiasm for action, and restraint of the senses can have this knowledge. And the very moment this knowledge dawns upon him, he is blessed with the ultimate peace, because after this there is left nothing more to strive for. After this he will never know anything other than peace.
