When Kṛṣṇa expands in fullness, that is called svāṁśa, viṣṇu-tattva. Just like Kṛṣṇa has expanded Himself as Viṣṇu, Nārāyaṇa, Vāsudeva, Saṅkarṣaṇa, Aniruddha, so many, millions. There is no limit. That is called svāṁśa. And Kṛṣṇa expands as His energy—this material energy, this material world, the spiritual world, spiritual energy, and we are also energy, marginal energy, taṭastha. Taṭastha means, marginal means . . . you can have a conception of marginal in the sea beach. The same place, walking, is sometimes covered with water and sometimes it is land. This is called marginal: between the water and the land. So we living entities, we are marginal. Sometimes we are under the protection of the spiritual energy, and sometimes we are under the protection of the material energy. We are under protection; we are not independent.
Therefore in the Bhagavad-gītā it is said, mahātmānas tu māṁ pārtha daivīṁ prakṛtim āśritāḥ (BG 9.13). So mahātmās . . . mahātmās means those who have realized God, not this politician mahātmā. No. Mahātmā means . . . mahātmās description is there in the Bhagavad-gītā, mahātmānas tu māṁ pārtha daivīṁ prakṛtim āśritāḥ: "They are under the spiritual energy." They are not under the material energy. They are not mahātmā; they are demons. So we are describing about the demons. Under the spiritual energy, one can understand his position, his relationship with God. Therefore it is said, mahātmānas tu māṁ pārtha daivīṁ prakṛtim āśritāḥ. And what is the sign? Bhajanty ananya-manaso jñātvā mām, avyayam. Their business is bhajana.
