If your heart is purified by this śravanaṁ kīrtanam method, ceto-darpaṇa-mārjanam (CC Antya 20.12), then the heart will be purified. And God is situated within your heart. Then, as soon as your heart is purified, you'll be able to see God within yourself, within your heart. That is called meditation. You see God within yourself and see constantly, "Here is God. Here is Kṛṣṇa." That is meditation.
So premāñjana-cchurita-bhakti-vilocanena santaḥ sadaiva hṛdayeṣu vilokayanti (Bs. 5.38). Santaḥ, saintly persons, or mahātmā, they develop by hearing about God constantly. They develop love of God. That is the aim of life. That is the real purpose of human life. Premā pum-artho mahān. Caitanya Mahāprabhu recommended that what is the actual benefit of this human form of life: to develop our dormant love for God. That is wanted, not to accumulate money. Nothing will go with us. Everything will remain. The bank balance will remain in the bank, and we have to go, and there will be fight amongst the claimanants. So that will be created. But nothing will go with you. Simply your consciousness, Kṛṣṇa consciousness, will help you. At the time of death, if you remember Kṛṣṇa . . . yaṁ yaṁ vāpi smaran loke tyajaty ante kalevaram (BG 8.6). Some way or other, if you remember at the time of death Kṛṣṇa, then your life is successful. So it doesn't matter whether you remain outside home or inside home, what is your occupation, but do not forget your real business. This is the Kṛṣṇa consciousness movement.
