Caitanya Mahāprabhu said it is just like a bag of mustard seeds, and this universe is only one seed. So Kṛṣṇa in His one plenary portion, Mahā-Viṣṇu, He is lying on the Causal Ocean, and during His breathing period, exhaling period, innumerable universes are coming out. These are the statements of Vedic literature, Mahā-Viṣṇu.
- yasyaika-niśvasita-kālam athāvalambya
- jīvanti loma-vilajā jagad-aṇḍa-nāthāḥ
- viṣṇur mahān sa iha yasya kalā-viśeṣo
- govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
- (Bs. 5.48)
So here it is stated by Kṛṣṇa, mayy āsakta-manāḥ. How we can become attached to Kṛṣṇa? You have to think over. Kṛṣṇa's different features, His name, His quality, His pastimes, His form, His entourage—so many things—you can simply think over. That is practical and actual meditation. If you study Vedic literature, you get so many information about Kṛṣṇa. And all these will be revealed to you. Svayam eva. Sevonmukhe hi jihvādau svayam eva sphuraty adaḥ (Brs. 1.2.234).
We cannot understand Kṛṣṇa by our speculative knowledge. If we try to do that, then we can approach up to the impersonal Brahman feature of Kṛṣṇa. Brahmeti. That is not full Kṛṣṇa. That is Kṛṣṇa's partial realization. Brahman realization means Kṛṣṇa's partial realization. Kṛṣṇa says in the Bhagavad-gītā, brahmaṇo 'haṁ pratiṣṭhā: "The Brahman, the all-pervading Brahman, impersonal Brahman, is situated in Me." That's a fact.
