Meditation means
Srimad-Bhagavatam
SB Canto 4
SB 4.6.33, Purport:
In this verse the word mahā-yogamaye is very significant. Yoga means meditation on the Supreme Personality of Godhead, and mahā-yoga means those who engage in the devotional service of Viṣṇu. Meditation means remembering, smaraṇam. There are nine different kinds of devotional service, of which smaraṇam is one process; the yogī remembers the form of Viṣṇu within his heart. Thus there were many devotees engaged in meditation on Lord Viṣṇu under the big banyan tree.
