Everyone has a tendency to give something in charity; Kṛṣṇa says, "Give it to Me," and this means that all surplus money accummulated should be utilized in furthering the Kṛṣṇa consciousness movement. Nowadays people are very much inclined to the meditational process, which is not practical in this age, but if anyone practices meditating on Kṛṣṇa twenty-four hours by chanting the Hare Kṛṣṇa mantra round his beads, he is surely the greatest yogī, as substantiated by the Sixth Chapter of Bhagavad-gītā.
