The Gītā makes it clear that only the ‘flower of the heart’, free of all impurity, growing in the Mānasa lake, is fit to be offered to the Paramātma. That, it seems, is why Kṛṣṇa said to Arjuna, “Brother-in-law! Whatever work you do, whatever dāna you make, whatever you eat, offer it all to Me; that is, do ‘all karmas in the spirit of offering them to the Lord of all’. Then you will surely attain Me alone. I have no feelings of distinction. I have neither enemies nor friends. I am only the witness. Whoever seeks Me, serves Me and rejoices in Me, in them I dwell.”
