Śrīpāda Śrīdhara Svāmī has composed a nice verse in this regard, the meaning of which is as follows: "My dear Lord, I am a living entity perpetually disturbed by the conditions of material existence. I have been cracked to pieces by the smashing wheel of material existence, and because of my various sinful activities while existing in this material world, I am burning in the blazing fire of material reactions. Somehow or other, my dear Lord, I have come to take shelter under Your lotus feet. Please accept me and give me protection." Śrīla Narottama dāsa Ṭhākura, also, prays like this: "My dear Lord, O son of Nanda Mahārāja, associated with the daughter of Vṛṣabhānu, I have come to take shelter under Your lotus feet after suffering greatly in the material condition of life, and I pray that You please be merciful upon me. Please do not kick me away, for I have no other shelter than You."
The conclusion is that any process of self-realization or God realization other than bhakti-yoga, or devotional service, is extremely difficult. Taking shelter of devotional service to the Lord in full Kṛṣṇa consciousness is therefore the only way to become free from the contamination of material, conditioned life, especially in this age. Those who are not in Kṛṣṇa consciousness are simply wasting their time, and they have no tangible proof of spiritual life.
