Altpath gives good advice, devotion is the element of our consciousness that is magnetic to the concept of divinity and God-forms.
Another thing you might consider is to embody the qualities of said deity as much as possible. Understand what they represent - they are idealized human images, essentially; the perfect warrior, the perfect mother, the perfect whatever - and what qualities they embody. Doing this polarized your personality and character towards the deity in question, and they will be more likely to appear for conversation, instruction, etc. It is a form of passive invocation, after a fashion, but is also a good ritual for summoning a deity - take the week before the ritual proper to embody that being, and then when you do the summoning, calling, invocation, etc., they will be more 'in line' with your consciousness and more likely to react to your entreaty.
Wonder why peoples of the old world relied on the priest/priestesses of a particular deity for communion and blessing with those beings? There you go. Of course, it all used to be a mystery to the average individual, these days you can go to any exceptional forum on the web and find this stuff out. Shame what the worlds come to, eh? (IMG:
