If formless meditation is difficult, then think of my form just as you see it here. With such meditation, the difference between subject and object is lost and the mind dissolves in unity.
To get the knowledge (realization) of the self, dhyana (meditation) is necessary. if you practice it continuously, the vrittis (thoughts) will be pacified. being quite desireless, you should meditate on the lord, who is in all the creatures, and when the mind is concentrated, the goal will be achieved.
For seeing brahman (realising the self) one has to give five things, (i.e. surrender five things) (1) five pranas (vital forces), (2) five senses (five of action and five of perception), (3) mind, (4) intellect and (5) ego. this path of brahma-jnana of self-realisation is ‘as hard as to tread on the edge of a razor.
