Yoga system means a process which helps uniting with the Supreme. That is called yoga system. But when there is spontaneous love, that is not a yoga system; it is yoga already. United. The Māyāvādī philosophers, they say that united means the individual soul has no more any separate existence, monism. They become one. But Vaiṣṇava philosophy, they say they become one, but at the same time they remain separate.
So these things are to be realized. As we make advance in spontaneous love for God, then these things become automatically revealed. It is . . . simply by theoretical exposition they cannot be understood. Therefore we have to practice. Vidhi-mārga . . . that vidhi-mārga is called bhakti-yoga. Vidhi-mārga means by following the regulative principles of śāstra, orders of the spiritual master, when we engage ourself in devotional service, that is called vidhi-mārga.
So we should not at once try to rise up to the rāga-mārga, or spontaneous. It is not an artificial thing. When one is, I mean to say, raised to the platform of spontaneous love, there is no question of falling back. During rāga-mārga, or regulative principle, there is chance of falling back, because that is not mature. But when it is mature, then there is no falldown. At that time, without Kṛṣṇa, without serving Kṛṣṇa, nobody can live.
Just like Caitanya Mahāprabhu, He said that, "I have no love for Kṛṣṇa." Just try to understand. Caitanya Mahāprabhu said that, "I have no love for Kṛṣṇa." Why? Then why You are crying? So Caitanya Mahāprabhu says: "I am crying just to make a show to others that I am a devotee. Actually I am not a devotee. If I would have been actually devotee, how I am living without Kṛṣṇa? I should have died." This is ecstasy. "If I had any love for Kṛṣṇa, how I am living without Kṛṣṇa? That means I do not love Kṛṣṇa."
