In plain words
Even so, from just a little sādhana you can gain a great reward.
In the other yugas, God's grace, the vision of God face to face, came only after people had done tapas for hundreds of years and let their bodies become anthills. Dhruva, at six years, gave up every tie, went to the forest and did fierce tapas, and only then could he win the blessings of Śrīman Nārāyaṇa. In these times, a man of fifty years cannot sit absorbed in dhyāna even for five minutes. And on top of that, vexation, anger, despair that he has not had the vision of God! Prahlāda, of tender years, does not bring tears to his eyes at the terrible tortures his father inflicts, is not seized with fear and trembling; again and again he praises, “O You who recline on the serpent, O Destroyer of the demons, O Lord of the world, O great Refuge of the afflicted, O Purifier of all,” that is all!
Turn the mind to Mādhava, do every task as service to Him, and no pain of any kind remains. The pain in the body, the thirst of the senses: you must accept these as God's prasāda, without letting them touch the heart. Dhyāna on God alone is the highest yoga of all. Through dhyāna comes the strength to give up everything. “Dhyānāt karma phalatyāgaṃ, tyāgāt śāntiranantaraṃ”. Dhyāna means the journey inward. The senses carry on their work only through the will. So, if you offer every act of will to God alone, all the senses come to a standstill.
