In Kali-yuga, chanting Hare Krishna remains the only practical path to realize Krishna and return home to Godhead.Listen — Srila Prabhupada Uvaca
Bhagavad-gītā 7.9 — March 26, 1972, Bombay 720326BG-BOMBAY [40:22 Minutes] Bg-07.09_720326BG-BOMBAY Prabhupāda: ...jīvanaṁ sarva-bhūtānām jīvanaṁ sarva-bhūteṣu tapaś cāsmi tapasviṣu [Bg. 7.9] So if we want to realize God, it is very simple; there is no difficulty. But unfortunately we do not want. That is our disease. Somebody has objection to go to the temple: "Why shall I go to the temple?" That's all right, you do not go to the temple, but what is the harm to think of Kṛṣṇa, or God, when you drink water? What is the loss?
Suppose while you are drinking water, and as it is said in the Bhagavad-gītā, raso 'ham apsu kaunteya [Bg. 7.8], that taste, that nice taste of water, is God. So if we remember, smaraṇaṁ... Smaraṇaṁ is one of the process of devotional service. śravaṇaṁ kīrtanaṁ viṣṇoḥ smaraṇaṁ pāda-sevanam arcanaṁ vandanaṁ dāsyaṁ sakhyam ātma-nivedanam [SB 7.5.23] So we can adopt either of all these processes—one, two, three, four, five, six, seven, eight, nine. Even one is sufficient.
If you cannot execute the nine different processes, one is also sufficient. It is so easy. Just like Parīkṣit Mahārāja, he was warned that within seven days he will meet with death. He was cursed by so-called brāhmaṇa boy. He was cursed.
Parīkṣit Mahārāja accepted that, and he was preparing himself for death. That is our Vedic process: until the next death comes, we have to prepare ourself for the next birth. Not that we shall die like cats and dogs. No.
There is a chain of progressive march, from aquatics to plant life, trees' life, then insect life, then birds' life, then beasts' life, then human form of life. Then you can promote further yourself to the higher planetary system: Tapaloka, Janaloka, Svargaloka, Maharloka, there are human beings. They are also human being, but with great intellect, the standard of happiness better, far, far better, thousand times better. As you go more and more on the upper planetary system, you get more and more standard of living, higher, up to Brahmaloka. But nowhere you can get immortality.
That is not possible. If you want immortality, then you will have to go to the Vaikuṇṭhaloka, far, far away from this material world. paras tasmāt tu bhāvo 'nyo 'vyakto 'vyaktāt sanātanaḥ [Bg. 8.20] That is sanātanaḥ dharma. So anywhere you like, you can go, but you have to prepare yourself. They are trying to go to the moon planet, but it is not so easy. Moon planet, so far we get information from the Vedic literature, that is also one of the heavenly planets.
There the inhabitants live for ten thousands of years. These descriptions are there. Now, how you can enter moon planet without being qualified for it? Suppose if you want to go to America, they have got their immigration department, and they very scrutinizingly, they examine whether you can be admitted as an immigrant or citizen, or even as visitor. So if so much restrictions are there within this planet, how do you expect there is no restriction and you can enter the higher planetary system by your whim?
