and (the five gross material elements and the ten acting and knowledge-gathering senses) — SB 6.4.27-28plugin-autotooltip__small plugin-autotooltip_bigŚrīmad Bhāgavatam 6.4.27-28
Just as great learned brāhmaṇas who are expert in performing ritualistic ceremonies and sacrifices can extract the fire dormant within wooden fuel by chanting the fifteen Sāmidhenī mantras, thus proving the efficacy of the Vedic mantras, so those who are actually advanced in consciousness—in other words, those who are Kṛṣṇa conscious—can find the Supersoul, who by His own spiritual potency is situated within the heart. The heart is covered by the three modes of material nature and the nine material elements [material nature, the total material energy, the ego, the mind and the five objects of sense gratification], and also by the five material elements and the ten senses. These twenty-seven elements constitute the external energy of the Lord. Great yogīs meditate upon the Lord, who is situated as the Supersoul, Paramātmā, within the core of the heart. May that Supersoul be pleased with me. The Supersoul is realized when one is eager for liberation from the unlimited varieties of material life. One actually attains such liberation when he engages in the transcendental loving service of the Lord and realizes the Lord because of his attitude of service. The Lord may be addressed by various spiritual names, which are inconceivable to the material senses. When will that Supreme Personality of Godhead be pleased with me?
