"Just like a child, when he learns walking, he requires little help. He may fall down, but that doesn't matter. He again stands up. Similarly, in the beginning there may be childlike falldown, but if you stick to the position, then one day you'll be able to walk freely, without any hamper. So this mantra, apavitraḥ pavitro vā sarvāvasthām, any condition of life, you can simply remember Puṇḍarīkākṣam, Kṛṣṇa. As soon as you chant "Kṛṣṇa," you remember everything.

So this remembering is the whole thing. If you have got always within your heart Kṛṣṇa, by sound or by mental thoughts, by work, some way or other, by reading books, any way, if simply you keep your consciousness in Kṛṣṇa, then your life is successful. That's all. And in the Bhagavad-gītā such person who is keeping always Kṛṣṇa within himself, he's certified as the greatest of all yogis."
