"So you have got this opportunity, Kṛṣṇa consciousness. Everything is explained in the Bhagavad-gītā, what is what. Do not lose this opportunity. Do not be foolish, misled by so-called scientists or philosophers or politicians. Take to Kṛṣṇa consciousness. And that is possible only guru-kṛṣṇa-kṛpāya (CC Madhya 19.151). By the mercy of guru and by the mercy of Kṛṣṇa you can achieve all success. This is the secret.
yasya deve parā bhaktir
yathā deve tathā gurau
tasyaite kathitā hy arthāḥ
So this guru-pūjā which we are doing, it is not self-aggrandizement; it is real teaching. You sing daily... What is that? Guru-mukha-padma-vākya..., āra nā kariyā aikya.Bās, this is perfection. I tell you frankly that whatever little success is there in this Kṛṣṇa consciousness movement, I simply believed what was spoken by my Guru Mahārāja, that's all. You also continue that, then every success will come."
